This initiative calls for sponsors and investigators of abandoned studies to publish unreported trials or to republish those trials with concerns over their findings.<\/p>\n<p>Using publicly available clinical study reports, other publicly available documents, and individual patient data, along with 77 000 pages of de-identified individual case report forms, the RIAT authors reconstructed the 329 trial. The original 329 trial publication reported 265 adverse events with paroxetine compared to the restored trial&#8217;s 481 events. Also, the original publication only reported 5 suicidal and self-injurious behaviours in the 93 participants on paroxetine; the RIAT paper\u2014after detailed examination of the case report forms\u2014reported 11 such events.<\/p>\n<p>This reanalysis provides some insight into why GSK, in 2012, <a href=\"http:\/\/www.justice.gov\/opa\/pr\/glaxosmithkline-plead-guilty-and-pay-3-billion-resolve-fraud-allegations-and-failure-report\">paid a fine of $3bn, part of which was for the\u00a0unlawful promotion of paroxetine<\/a> for patients under the age of 18. But it also questions the fundamental nature and basis of clinical research, the ethical principles underpinning research\u2014including the impact conflicts of interest have on distorting the truth\u2014and a journal publication process that, at times, allows inaccuracies to persist.<\/p>\n<p>What is promptly needed to restore public trust is an overhaul of the current trial publication system. Journals should openly allow corrections and comments to be addressed: science should be self-correcting. Otherwise, we end up with a situation where an incorrect study, <a href=\"https:\/\/scholar.google.co.uk\/scholar?cites=7589903240306694483&amp;as_sdt=2005&amp;sciodt=0,5&amp;hl=en\">cited 576 times<\/a> (oops, and 577 times if you are reading this), remains in the public domain, further reinforcing public suspicion over clinical trial results; making it more difficult to discern beneficial effects from harmful ones.<\/p>\n<p><em><strong>Carl Heneghan<\/strong> is <a href=\"http:\/\/www.phc.ox.ac.uk\/team\/researchers\/carl-heneghan\">professor of EBM<\/a> at the University of Oxford, <a href=\"http:\/\/www.cebm.net\/\">director of CEBM<\/a>, and a GP.<\/em><\/p>\n<p><em>His research interests span chronic diseases, diagnostics, use of new technologies, and investigative work with <\/em>The BMJ<em> on drugs and devices that you might stumble across in the media.
