Chalmers I, Glasziou P, Goodle F. All trials must be registered and the results published. BMJ 2013;346:f105
Under-reporting of research can lead to overestimates of the benefits of treatments and underestimates of their harmful effects. Failure to publish all the results from clinical trials distots the evidence base for clinical decisions. The responsibilities of authors are clear, but there is also clear and consistent evidence that academics and non-commercial funders are just as guilty as industry.
