About Evidence-Based Medicine - When It's For Real, And When It's Just Advertising
Especially on the difference between real evidence-based medicine, and advertising by pharma companies for their products - and there seems to be a lot of that nowadays...
First, a short bit, recently:
The British Medical Journal article to which the above refers:
“The advent of evidence based medicine was a paradigm shift intended to provide a solid scientific foundation for medicine. The validity of this new paradigm, however, depends on reliable data from clinical trials, most of which are conducted by the pharmaceutical industry and reported in the names of senior academics. The release into the public domain of previously confidential pharmaceutical industry documents has given the medical community valuable insight into the degree to which industry sponsored clinical trials are misrepresented.1234 Until this problem is corrected, evidence based medicine will remain an illusion.
…
The pharmaceutical industry’s responsibility to its shareholders means that priority must be given to their hierarchical power structures, product loyalty, and public relations propaganda over scientific integrity. Although universities have always been elite institutions prone to influence through endowments, they have long laid claim to being guardians of truth and the moral conscience of society. But in the face of inadequate government funding, they have adopted a neo-liberal market approach, actively seeking pharmaceutical funding on commercial terms. As a result, university departments become instruments of industry: through company control of the research agenda and ghostwriting of medical journal articles and continuing medical education, academics become agents for the promotion of commercial products.6 When scandals involving industry-academe partnership are exposed in the mainstream media, trust in academic institutions is weakened and the vision of an open society is betrayed.
The corporate university also compromises the concept of academic leadership. Deans who reached their leadership positions by virtue of distinguished contributions to their disciplines have in places been replaced with fundraisers and academic managers, who are forced to demonstrate their profitability or show how they can attract corporate sponsors. In medicine, those who succeed in academia are likely to be key opinion leaders (KOLs in marketing parlance), whose careers can be advanced through the opportunities provided by industry. Potential KOLs are selected based on a complex array of profiling activities carried out by companies, for example, physicians are selected based on their influence on prescribing habits of other physicians.7 KOLs are sought out by industry for this influence and for the prestige that their university affiliation brings to the branding of the company’s products. As well paid members of pharmaceutical advisory boards and speakers’ bureaus, KOLs present results of industry trials at medical conferences and in continuing medical education. Instead of acting as independent, disinterested scientists and critically evaluating a drug’s performance, they become what marketing executives refer to as “product champions.” …
Regulators receive funding from industry and use industry funded and performed trials to approve drugs, without in most cases seeing the raw data. What confidence do we have in a system in which drug companies are permitted to “mark their own homework” rather than having their products tested by independent experts as part of a public regulatory system? Unconcerned governments and captured regulators are unlikely to initiate necessary change to remove research from industry altogether and clean up publishing models that depend on reprint revenue, advertising, and sponsorship revenue.
Our proposals for reforms include: liberation of regulators from drug company funding; taxation imposed on pharmaceutical companies to allow public funding of independent trials; and, perhaps most importantly, anonymised individual patient level trial data posted, along with study protocols, on suitably accessible websites so that third parties, self-nominated or commissioned by health technology agencies, could rigorously evaluate the methodology and trial results. With the necessary changes to trial consent forms, participants could require trialists to make the data freely available. The open and transparent publication of data are in keeping with our moral obligation to trial participants—real people who have been involved in risky treatment and have a right to expect that the results of their participation will be used in keeping with principles of scientific rigour. Industry concerns about privacy and intellectual property rights should not hold sway.” https://www.bmj.com/content/376/bmj.o702

And this is a problem of long standing, it didn’t arise with the Plague and the “Vaccines”:
The above lecture is from ten years ago…
And here’s a rather technical look at the problem from 2005: “There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.
Published research findings are sometimes refuted by subsequent evidence, with ensuing confusion and disappointment. Refutation and controversy is seen across the range of research designs, from clinical trials and traditional epidemiological studies [1–3] to the most modern molecular research [4,5]. There is increasing concern that in modern research, false findings may be the majority or even the vast majority of published research claims [6–8]. However, this should not be surprising. It can be proven that most claimed research findings are false. Here I will examine the key factors that influence this problem and some corollaries thereof.“ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1182327/
