Median time from completion of a clinical trial to publication of results in a peer-reviewed journal is 21 months, according to a study published online March 4 in JAMA Internal Medicine.
Past studies have shown that 50% to 75% of clinical trial results are published in peer-reviewed biomedical journals, most within 2 to 2.5 years.
The researchers conclude that the small differences among trial types indicate that “timely dissemination of research needs to be uniformly prioritized to enhance science.” They support current federal initiatives requiring reporting results within a year of completion of a clinical trial. However, the investigators point out how much must be accomplished during that year, including compiling data, performing statistical analysis, writing, preparing figures, and allowing time for peer review.
