Only a person that does not understand how the medical profession works would blindly trust medical studies. You appear to be one of them.

Medical schools and curriculum were taken over by the corporations and foundations that funded them in the early 1900's and they've been indoctrinating medical students ever since.

“The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness.” - Dr. Richard Horton, the current editor-in-chief of the Lancet – considered to be one of the most prestigious peer-reviewed medical journals in the world.

“It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of the New England Journal of Medicine” - Dr. Marcia Angell, a physician and longtime Editor in Chief of the New England Medical Journal (NEMJ), which is considered to be one of the most prestigious peer-reviewed medical journals in the world.

“The medical profession is being bought by the pharmaceutical industry, not only in terms of the practice of medicine, but also in terms of teaching and research. The academic institutions of this country are allowing themselves to be the paid agents of the pharmaceutical industry. I think it’s disgraceful.” – Arnold Seymour Relman (1923-2014), Harvard Professor of Medicine and Former Editor-in-Chief of the New England Medical Journal
