This question comes off the back of an answer to this question where there was reference to a retraction of an article in The Lancet based on inaccuracies and fraudulent data.
As a lot of research (if not all) are funded by interested parties such as pharmaceutical companies, the legal profession, etc. I was wondering if there are any articles released which has results in opposite to the best interest of the funding organisation(s)?
One example I have recently found by chance within the fields of Psychology and Neuroscience involves using Vagus Nerve Stimulation (VNS) to treat difficult-to-treat depression (DTD). Due to the amount of research with conflicts of interest concerning manufacturer(s) of VNS equipment, it is hard if not impossible to find any research completely free of the possible influence the manufacturer(s) have had so far.
Here I am looking for any examples which will show that there is medical research which is completely impartial and not necessarily just the example here.
