Recently, I received this comment from a reader:

Edzard-‘I see you do not understand much of trial design’ is true BUT I wager that you are in the same boat when it comes to a design of a trial for LBP treatment: not only you but many other therapists. There are too many variables in the treatment relationship that would allow genuine , valid criticism of any design. If I have to pick one book of the several listed elsewhere I choose Gregory Grieve’s ‘Common Vertebral Joint Problems’. Get it, read it, think about it and with sufficient luck you may come to realize that your warranted prejudices against many unconventional ‘medical’ treatments should not be of the same strength when it comes to judging the physical therapy of some spinal problems as described in the book.

And a chiro added:

EE: I see that you do not understand much of trial design

Perhaps it’s Ernst who doesnt understand how to research back pain.

“The identification of patient subgroups that respond best to specific interventions has been set as a key priority in LBP research for the past 2 decades.2,7 In parallel, surveys of clinicians managing LBP show that there are strong views against generic treatment and an expectation that treatment should be individualized to the patient.6,22.”

Journal of Orthopaedic & Sports Physical Therapy
Published Online:January 31, 2017Volume47Issue2Pages44-48

Do I need to explain why the Grieve book (yes, I have it and yes, I read it) is not a substitute for evidence that an intervention or technique is effective? No, I didn’t think so. This needs to come from a decent clinical trial.

And how would one design a trial of LBP (low back pain) that would be a meaningful first step and account for the “many variables in the treatment relationship”?

How about proceeding as follows (the steps are not necessarily in that order):

  • Study the previously published literature.
  • Talk to other experts.
  • Recruit a research team that covers all the expertise you need (and don’t have yourself).
  • Formulate your research question. Mine would be IS THERAPY XY MORE EFFECTIVE THAN USUAL CARE FOR CHRONIC LBP? I know LBP is but a vague symptom. This does, however, not necessarily matter (see below).
  • Define primary and secondary outcome measures, e.g. pain, QoL, function, as well as the validated methods with which they will be quantified.
  • Clarify the method you employ for monitoring adverse effects.
  • Do a small pilot study.
  • Involve a statistician.
  • Calculate the required sample size of your study.
  • Consider going multi-center with your trial if you are short of patients.
  • Define chronic LBP as closely as you can. If there is evidence that a certain type of patient responds better to the therapy xy than others, that might be considered in the definition of the type of LBP.
  • List all inclusion and exclusion criteria.
  • Make sure you include randomization in the design.
  • Randomization should be to groups A and B. Group A receives treatment xy, while group B receives usual care.
  • Write down what A and B should and should not entail.
  • Make sure you include blinding of the outcome assessors and data evaluators.
  • Define how frequently the treatments should be administered and for how long.
  • Make sure all therapists employed in the study are of a high standard and define the criteria of this standard.
  • Train all therapists of both groups such that they provide treatments that are as uniform as possible.
  • Work out a reasonable statistical plan for evaluating the results.
  • Write all this down in a protocol.

Such a trial design does not need patient or therapist blinding nor does it require a placebo. The information it would provide is, of course, limited in several ways. Yet it would be a rigorous test of the research question.

If the results of the study are positive, one might consider thinking of an adequate sham treatment to match therapy xy and of other ways of firming up the evidence.

As LBP is not a disease but a symptom, the study does not aim to include patients that all are equal in all aspects of their condition. If some patients turn out to respond better than others, one can later check whether they have identifiable characteristics. Subsequently, one would need to do a trial to test whether the assumption is true.

Therapy xy is complex and needs to be tailored to the characteristics of each patient? That is not necessarily an unsolvable problem. Within limits, it is possible to allow each therapist the freedom to chose the approach he/she thinks is optimal. If the freedom needed is considerable, this might change the research question to something like ‘IS THAT TYPE OF THERAPIST MORE EFFECTIVE THAN THOSE EMPLOYING USUAL CARE FOR CHRONIC LBP?’

My trial would obviously not answer all the open questions. Yet it would be a reasonable start for evaluating a therapy that has not yet been submitted to clinical trials. Subsequent trials could build on its results.

I am sure that I have forgotten lots of details. If they come up in discussion, I can try to incorporate them into the study design.

  • Edzard- thank you very much for your detailed exposition of what will constitute a reliable trial of a treatment for LBP. Grieve’s book or any other is not a substitute for anything. It is a compendium of his life’s work and experience in the field. There can be no objection to a well conducted clinical trial of anything BUT it’s results cannot be a final word on such a complex subject as LBP ( or most other things also). Grieve’s book (2nd edition) lists more than 2500 references and recognizes the galaxy of opinions and conclusions and conflicting hypotheses that they contain. Assuming for the moment that no such trial meets or has met your satisfaction do you think that Grieve’s and others’ lifetimes work in the field and the positive experiences of countless patients count for nothing and have no validity for efficacy? If you do think ‘there may be something in it!’, on what evidence would you base this view or conclusion?

    • Oscar Wilde said: “Experience is the name we give to our mistakes.”
      I’d say that experience can often be the name healthcare professionals give to their mistakes; it is far too unreliable to be taken for evidence in healthcare. that is not to say that it is useless – quite to the contrary! It can be an invaluable starting point for research.

      • Another quote is germane to chiros and evidence:

        “It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
        ― Upton Sinclair, I, Candidate for Governor: And How I Got Licked

        • Alan-Sinclair’s quote of course has some validity, more so with some than others, but comes nowhere near close to all the other psychological and many other factors that result in our ‘understanding’ of something. It might be considered an extreme oversimplification.

          • It does raise the question as to where is the persuasive, robust evidence for chiropractic? If it is as effective as many chiros claim, where is the evidence that would convince even the most skeptical of skeptics? Why are chiros not striving to produce the evidence for the practice that so many are making their daily living out of? If they were able to produce that evidence, we might quickly see chiropractic departments opening up in every NHS hospital, relieving the burden on so many other departments, not to mention relieving the suffering of patients.

          • Alan- I have made no claim for persuasive, robust evidence for chiropractic in anything I have written nor will I. Nor do I answer for most anything they do except in the right hands have some expert competence in manipulative skills. I think what I have written should be clear: I asked about 4 repeated questions, all very easy to answer and received no reply from Edzard, except finally an ad hominem ‘twit’ reference. That’s OK because I don’t think it denigrates me but does make public flaws in his approach to these matters. I repeat, your concerns are not something I have alluded to nor have to answer for.

          • Alan- I have not , will not and cannot provide robust, persuasive evidence for all that is encompassed by chiropractic. All I originally contended was that in well trained chiropractic hands it was reasonable to assume they were capable of manipulation of joints are than those of the lower back. With the dialogue expanded this and most other straight forward questions of mine, although repeated, remain unanswered by Edzard. It has resulted in his ad hominem aside about a ‘belligerent twit’ . This attempt to denigrate me , sadly, publicly demeans him.

          • Chiropractic is a multimodal approach.

            Regarding the daily living…


            IMO the main issue re lack of robust research falls upon the colleges. When i was doing my research residency i was told that the research dept was not profitable…the college lost money every year on the dept. Of course grants and patents are the way to go if one can get them.

            Most chiro students enter to become chiropractors, not researchers.

            The CARL program is a good start IMO.

            I never said you did. But I hope you agree that the elusive nature of the evidence for what so many chiros are making a living out of is, at least, perplexing.

            I have not , will not and cannot provide robust, persuasive evidence for all that is encompassed by chiropractic.

            I didn’t really ask for that: but it would be good if chiros could make a start sometime.

            All I originally contended was that in well trained chiropractic hands it was reasonable to assume they were capable of manipulation of joints are than those of the lower back.

            Do you mean “other than those of the lower back”? But anyone can ‘manipulate’ joints: the question is whether any benefit outweighs the harms.

            And? All that might mean is that there are a number of different practices that chiros need to be researching and providing evidence for.

            Regarding the daily living…


            Not sure why that is relevant. It redirects to the UK site for me but this site gives the median salary for a chiro in the US as $154,000.

            IMO the main issue re lack of robust research falls upon the colleges. When i was doing my research residency i was told that the research dept was not profitable…the college lost money every year on the dept.

            It isn’t necessary that research be profitable: what matters is whether chiros have the evidence that what they do does more good than harm and that the training establishments are teaching what they know there is good evidence for.

            Of course grants and patents are the way to go if one can get them.

            Grants are not the only source of funding, of course, but what have patents got to do with it?

            Most chiro students enter to become chiropractors, not researchers.

            I don’t doubt it, but that’s just another excuse.

            “A good start”…

          • In my experience, chiro-research rarely gets funded because the applications lack scientific rigor.

          • @Edzard

            You’d have thought all chiros and trainers with an ounce of integrity would be doing all they can to publish robust evidence for what they do…

          • integrity seems to be the keyword here…

        • May not be limited to chiropractors…

          “Trial evidence for the other six procedures showed no benefit over non-operative care.”

      • Edzard- 2500 + references represents a whole lot of experience beyond any one person e.g Gregory Grieve: in fact not just experience but a whole variety of varied and conflicting evidence. It seems in answer to my question ‘is there something in it?’ that the only value you place on say Grieve’s work and many others is that it can be an invaluable starting point for research. And by that I presume you mean the RCT of which you expound so well and is of great value when possible. Without say any positive trial outcomes, so far, are there ANY other types of evidence that you could accept for the confident practice of a health care intervention? Without the ‘certainty’ or benefits outweighing risks trial or epidemiological findings, would you allow any treatment for a possible medical condition of your own? Where do you stand or what do you think about any acceptance of ‘doubtful’ medical practices? We would all prefer SBM but is it always possible? You will know by now that I think not!

        • of course, when no sound evidence is available one has no other choice than to go with less sound evidence.
          the principle is this: if you can, go with the best evidence that exists.

          • Edzard- I could not agree more with that sentiment but there may be, and we have, some disagreement about ‘sound evidence’. You may consider it possible to produce a RCT that will/could provide better evidence than other possibilities: in fact you seem to think it IS the best evidence , for or against a procedure. Better than all other evidence? I would agree IF it were possible to know exactly the anatomical and physiological location of the cause of the symptoms and have reproduceable exact skills , forces used etc. and in enough equivalent patients and therapists. In my humble view it is a minefield of uncertainty and will not produce the ‘best’ evidence for a procedure- for or against. It will be evidence but perhaps of no more strength than an expert clinician applying his skills and scientific knowledge to help an individual patient(s), and reporting the results. Far from perfect, but useful. The RCT, double blinded or not, is most suited to distinguish therapeutic value, among options, for example pharmacological substances and anything where the variables are controllable. I know you disagree .Oh and that question: ‘do you think there’s something in it and if so why’?

          • the best evidence is the one that is least open to bias.
            I have tried to show you in my post that the variables you mention are controllable.

          • Edzard-if the variables are controllable and the diagnosis of the origin of the cause of pain is established ( and there can be numerous possible structures involved with no consensus on these matters) then there must be some very good RCT( in your view?) regards low back pain. Do they establish any validity or otherwise of therapeutic manipulative treatments? Have you had experience within the ‘manipulation’ field that caused you to read 750+ pages of Grieve’s Common Vertebral Joint Problems,2nd edit.? His eclectic approach, using abundant scientific references and much else would seem to have minimized his bias. From your experience do you think there is any value , beyond placebo, in manipulative therapy of painful, restricted motion of vertebral joints and surrounding tissues? If not then we have nothing more to exchange on the subject but if you think there is some value- then WHY? So far you have not answered this question!

          • sorry – too many questions and no time

          • Edazard- there were just two crucial questions 1. anything in it? 2. if so why? There is a smatter of intellectual dishonesty here by avoidance of the questions that have been asked at least 3 times. I have enjoyed our exchanges.

          • “a smatter of intellectual dishonesty”
            oh dear!

          • Leonard,

            The man wrote a whole blog post just for you, patiently addressing your previous posts. And all you got to argue about is a 2nd edition of some textbook that was written in 1988 with no new edition thereafter. Other than hanging on to this 30+ year old textbook, do you not think that the field of chiropractic advanced in the last 30+ years? If you are unable to cite any new scientific studies in the field, then I seriously question as to what you are arguing about. Other than arguing for argument’s sake.

          • Jack-no new edition after 1988 because Gregory Grieve died, 2001. He had developed and progressed with and on giants shoulders and he wished for this to continue with a younger generation coming through. I only chose his book because it impressed me among so many other books in its organization, very clear writing and a great deal more. I am sorry that you do not understand the arguments and in future I will try to express myself in a clearer manner. If you read my original question to Edzard it stemmed from his comment about the competence of chiropracters to manipulate other than for the low back. The discussion expanded. I make no claim for chiropractors other than they use similar techniques ( although not necessarily identical) as osteopaths, physiotherapists, some orthopedics and other practitioners of the arts. In skilled hands they can be very effective for relief of painful and ‘stiff’ joints. Their science I will leave to others more qualified to comment.

          • Jack-no new edition [of Grieve] after 1988 because Gregory Grieve died, 2001.

            There is little hindrance to a reference of quality to be continued to be published in new editions, provided the copyright holders agree. Gray’s Anatomy continues to be published in new editions, even though its author, Henry Gray, died in 1861 and its illustrator, Henry Vandyke Carter died in 1897.

            It was first published in 1858 and is currently in its 42nd edition, published in 2020.

  • Usual care? That could get messy.

    “Those studies estimated that 28% (95% confidence interval, CI: 19.7–38.6) of health care for low back pain in Australia (based on 164 patients receiving 6488 care processes)5 and 32% (95% CI: 29.5–33.6) of health care for low back pain in the United States of America (based on 489 patients receiving 4950 care processes)6 was discordant with clinical guidelines.”

    Bull World Health Organ. 2019 Jun 1; 97(6): 423–433.

  • Jack- advances in manipulation therapy will mainly be in the scientific domain not the actual physical techniques. To know about what I argue go back to my original question to Edzard which was simply about the reasonableness of allowing some competence of chiropractors in manipulation of joints other than the lower back. The discussion expanded- and yes Edzard was very patient and informative, until the very end when he dodged my two questions. If you think that a 30 year old medical textbook- which was just one of a selection- has no value in contributing knowledge to treating patients I’m afraid I will leave you in your ignorance.

    • Leonard, I am not commenting on whether a old text book can contribute to treating patients or not. But rather I am pointing out that when repeatedly asked to cite any new studies you dodge that and keep going back to a 30 year old textbook. It is hard to believe that are no advances in the fields that can add to the knowledge presented in the old textbook. All this makes me think that you don’t know of any new advances in the field or just don’t care to bring any to the conversation. Anyway, I will let you wallow in your outdated information.

      • Jack-thanks for that profound understanding of all that has transpired on this blog. Whoever said or was arguing that more modern texts wouldn’t have more up to date references. Suppose I select a more recent text ( of which I have many), not on chiropractic particularly, but manipulation in general and matters related, and notice numerous references, maybe hundreds, sighted after 1988, which ones would you prefer me to quote? If you like I’ll give you some text references and you can check for yourself. Your call.

        • you do know there is more up to date information available! You probably also know where to find it but choose not to cite any in two dozen or so posts you wrote in this discussion that spans multiple threads.

          Why are you asking me which up to date references you should be quoting? You started this discussion and you should be able to do that yourself without anyone’s help.

          While you were bickering and beating a dead horse with an old textbook, EE wrote a blog post on designing a trial on LBP and reviewed a trial on LBP. Maybe we call learn something from EE. I will take EE’s que and not engage with your any further. have a nice life!

      • Of course there is continued research. A simple place to start is a Google Scholar search.,50

  • Edzard- you took time to write ‘oh dear’ so why not instead answer the questions? Let me rephrase them. Do you dismiss manipulative treatment with the same strength as you do say homeopathy? If not, why not?

      • Edzard-you clearly have some difficulty with my questions and I think I know why you will not answer. I have read a bit on this very question in the past and was trying to get your opinion, which to the death you won’t answer. If I’m a twit by asking repeatedly a few questions you haven’t the courage to answer then I know I am in some very good company and do not take offence at your ad hominem aside.

      • Edzard- I have just finished your fascinating and informative book ‘A Scientist in Wonderland’. In the Addendum you state ‘Chiropractic or osteopathic spinal manipulation might well be useful for back and neck pain…’ which is part answer to the main questions I posed you. I would still like an answer, which I now know will not be forthcoming, to why you should think such a heretic notion!

    • That is Edzard typical response when he doesn’t want to answer a question.

      All one has to do is look at the many SR and MA on the topic re back pain. Most come to the same conclusion…SMT is as good or better than other approaches.

      Do we know exactly how it works? Nope. Some evidence of reduce muscle spasms, overall reduction in inflammation and activates descending inhibitory pain pathways.

      Best when combined with other approaches like rehab and exercise…which most chiropractors do.

      Current research is looking more into subgrouping and subtyping, responders vs nonresponders, clinical prediction rules, other conditions, etc.

      • not really!
        my standard response: when someone behaves like a bot and tries to insult me (“intellectual dishonesty”) I send him/her my blog post that indicates I had enough.
        I did answer about a dozen questions of this chap, had I continues answering what he called his last one, I fear, it would not have been his last.
        it certainly has nothing to do with me not wanting to answer a question.

        • Edzard- I didn’t have a ‘last question’ but I did repeat a question(s) several times which you failed to answer. I apologized for the ‘ intellectual dishonesty’ quip but there has to be some explanation for why you refuse to commit to an answer relating to whether you think there is anything of value in manipulative therapy and if so why do you think thus. If you think there is no value beyond what may be found in say exercise or massage, and this conclusion is based on sound , consensus agreed trials, then we have nothing further to discuss and will agree to differ. If you think there may be some value in manipulative therapy then my question is why such a belief? If it’s not a result of trial evidence as you have explained very well previously then it only leaves clinical evidence with all that that entails and which you seem not to value very highly.

  • Pharma found guilty again for the death of patients.

    “Purdue Pharma Is Dissolved and Sacklers Pay $4.5 Billion to Settle Opioid Claims”

    “Another fund will compensate 130,485 individuals and families of those who suffered from addiction or died from an overdose, in amounts ranging from $3,500 to $48,000. Guardians of about 6,550 children with a history of neonatal abstinence syndrome may each receive about $7,000.”

  • @Talker

    Bahh !!
    You talk too much.

    The point is that Pharma meds kill patients, as was proven in a court of law.

    • Pharma meds kill patients, as was proven in a court of law

      If you bothered to actually read and understand the article you quoted above in detail, you would know that nothing of that sort happened. Here is a quote from the same article where I bolded relevant text:

      While the settlement serves as a benchmark in the nationwide opioid litigation aimed at covering governments’ costs and compensating families, it also means that a full accounting of Purdue’s role in the epidemic will never unfold in open court. Purdue pleaded guilty to federal criminal charges for drastically downplaying OxyContin’s addictive properties and, years later, for soliciting high-volume prescribers.

      All Purdue is guilty of as proven in a court of law is that they downplayed the addictive properties. The article is about Purdue settlement and has nothing to do with pharma meds killing patients and nothing of that sort has been proven in the court of law.

      Your attempt to spin the Purdue settlement as a verdict on the entire pharma industry is laughably stupid.

      • @Talker

        Spin it anyway you choose.
        This pharma LOST…. lost in court, lost they’re business, lost billions of dollars, lost credibility.

        An admission of downplaying the addictive properties of a pain reliever that ends up killing patients…. IS an admission of guilt. Pleading guilty is the equivalent of being found guilty. Purdue Pharma pleased GUILTY…. rather than attempt to fight hundreds of thousands of cases individually. They admitted guilt in court…. therefor they are guilty. Do think they would have admitted guilt and the consequences of that if they were not ?

        A drug crisis that ends up killing patients is a serious matter for an industry(pharma) that is one, supposed to be giving medial relief to patients, two intended to do no harm.
        “In 2019, nearly 50,000 people in the United States died from opioid-involved overdoses.1 The misuse of and addiction to opioids—including prescription pain relievers, heroin, and synthetic opioids such as fentanyl—is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total “economic burden” of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.”

        • @Listener

          You are absolutely right! Pharma drugs kill people PERIOD! There is no argument about that. However, be patient my friend, it is only a matter of time when your dream will come true, and people will wake up and reject big-pharma, scientists and doctors that push pharma drugs and vaccines that are detriment to human living. It is already happening to some extent right now, lots of people are outright rejecting vaccines and dying of covid: While others are taking horse medicine in place of vaccine and ending up in hospitals: Whether you get the shot or horse medicine, big-pharma gets it beak wet and I don’t like that and I am sure you don’t either.

          If only we can go back to the medieval times of no pharma and no doctors, when the health care systems were successfully run by witch doctors and other black medicine practitioners that did not have to prove to anyone that their medicine works, anything they said was believed by masses of sheeple. Don’t get me wrong, people did die during the medieval era from diseases and plagues en masse, but most importantly they did not die due to pharma drugs. Like I said earlier people are waking up and smelling the Covfefe and my hero Prez. Trump can be credited for all that.

          In anticipation of return of those medieval health care systems, I started a company called No-Pharma Formulations LLC that prepares vial of “medicine” for all diseases that plague mankind. The vial contains pure water, but the label has the name of whatever medicine the patient needs, therefore it is devoid of side effects and patient cannot get addicted or overdose even if they intend to. You might be thinking, how is water going to cure diseases? It will my friend! Placebo effect! Look it up if you don’t believe me. Don’t be stupid enough to try and copy me, I already patented the technology behind my formulations, and I will sue your pants off.

          On the other hand, I would love to sell you some of my “medicine” that I am already manufacturing and stock piling on a large scale. I am willing to take orders and you will be my first customer and will get a huge discount. My “medicine” costs a lot but remember it is the cost of having no side effects, no death, no addiction etc. all of which big-pharma cannot promise if you take their meds.

          • @Honest-Ape
            For the most part, your rant is mere gibberish.
            To a couple of statements I will respond.

            1-Ape said;
            “Don’t get me wrong, people did die during the medieval era from diseases and plagues en masse, but most importantly they did not die due to pharma drugs.”

            Exactly mate, now you’ve got the idea !

            2-Ape said;
            “While others are taking horse medicine in place of vaccine and ending up in hospitals”

            I will say first that those that have already been infected with Covid-19 and recovered have no reason to be jabbed. Natural immunity is equal or better than any of the vaccines being administered. Please don’t argue the point and compel me to post a list of links.

            In addition to that, you are immensely wrong in your condemnation of Ivermectin. You’re so far from the truth that you appear dumb. To think that an ape like you could fall for the lie that Ivermectin is drug only for animals. Might I add that you are guilty of the spreading of misinformation. You obviously fell for the favorite media narrative of the FDA WHO & CDC …. LIES !

            “Ivermectin, ‘Wonder drug’ from Japan: the human use perspective”
            “There are few drugs that can seriously lay claim to the title of ‘Wonder drug’, penicillin and aspirin being two that have perhaps had greatest beneficial impact on the health and wellbeing of Mankind. But ivermectin can also be considered alongside those worthy contenders, based on its versatility, safety and the beneficial impact that it has had, and continues to have, worldwide—especially on hundreds of millions of the world’s poorest people. Several extensive reports, including reviews authored by us, have been published detailing the events behind the discovery, development and commercialization of the avermectins and ivermectin (22,23-dihydroavermectin B), as well as the donation of ivermectin and its use in combating Onchocerciasis and lymphatic filariasis.1–6) However, none have concentrated in detail on the interacting sequence of events involved in the passage of the drug into human use.”

            Read it ans weep … YOU FOOL !
            Weep for all the millions that have died while they didn’t need to die.


            Ivermectin is estimated to have been dosed over three billion times with an excellent safety record.


          • Listener- you seem to have it completely wrong with your view of Ivermectin. For a series of analyses by David Gorski ( Orac) with many references and some very good reader comments I refer you to the blog ‘Respectful Insolence’ which if studied carefully should change your mind, if it is open enough.

          • @Listener

            LOL!! You sound like a big-pharma shill, hawking ivermectin.

            How do you arrive at singing praises of a pharma med like ivermectin, after making this bold overarching statement about pharma meds?

            Pharma meds kill patients, as was proven in a court of law

            Cognitive dissonance you display is quite jarring!!

            On the scientific front, a new study came out with the following conclusion:

            “There was a significant drop in the sperm counts of the patients after their treatment with Ivermectin,”

            On the legal front this happened. Here is what the judge said (emphasis mine):

            “After considering all of the evidence presented in this case, there can be no doubt that the medical and scientific communities do not support the use of ivermectin as a treatment for COVID-19,” Judge Michael A. Oster wrote in the new ruling, issued Monday.

            If we apply Listener’s illogical logical methods and reasoning, we can safely conclude the following: Ivermectin does not work as a treatment for COVID-19, as was proven in the a court of law

          • @HA

            Excellent. What a surprise that Listener completely fails to grasp your point.

          • @Deaf Idiot Listener

            Ivermectin is estimated to have been dosed over three billion times with an excellent safety record.

            Yes, it’s a wonderful drug, getting rid of all sorts of nasty parasites. BUT NOT THE COVID-19 VIRUS.

            And oh, you know what else has been dosed over three billion times with an even BETTER safety record? Covid-19 vaccines.
            And, quite contrary to Ivermectin, these vaccines WORK – and that with just two doses, instead of the chronic use as advocated by the extremely stupid pushers of this antiparasitic drug.

            But thank you again for yet another excuse to slap you around the head with your own foolishness (and, apparently, deafness, as you keep regurgitating the same old long-debunked rubbish over and over again).

    Ahhhh …. Richard
    Still you are not onboard with the program… are ya.

    You’ve still got more homework to do.
    Go to the corner, and when you’ve finished reviewing this material we can speak again.

    • To all

      C’mon floks… where does the madness end ?
      How much more can we be convince that the vaccines are not effective ? When will they begin promoting the fifth dose ? It’s not even feasible to keep jabbing patients every few months.

      Can we begin talking about some therapeutics ? … finally.
      It has been over eighteen months since the pandemic began. Still NOBODY today is even talking about changing diet and consumption to lessen the threat that comorbidities effect on the infected patients. In the eighteen months that have past, millions of patients could have lessened the chance of dying by simply loosing the fat and excess weight. Reducing insulin resistance, lowing the body demand on oxygen by reducing mass, improving the immune system response.

    • @Deaf idiot Listener
      ivmmeta is a collection of wildly unprofessional, partly retracted and ostensibly even fraudulent mess-ups that do not even deserve the word ‘study’. It is long-debunked rubbish, as the world’s leading medical journals such as the BMJ also concluded.

      And once again: you implicitly suggest that we medicate all unvaccinated people around the world with this stuff for the rest of their life? Now that would be monumentally stupid, given the fact that we have perfectly good vaccines that do a far better job. I’d almost suspect that you are a pharma shill with money invested in Ivermectin manufacturers – but no, you are likely just a dumb troll who tries to annoy people by trotting out the same stupid nonsense over and over and over again …

      @Edzard: I suggest you block this buffoon on this thread, as his relentless Covid-related propaganda has nothing to do with low back pain trials, and thus is completely off-topic.
