Epilepsy Research Reporting May Be Biased

Epilepsy Res; ePub 2018 Mar 30; Rayi et al.


 

A cross-sectional analysis of epilepsy intervention trials suggests there may be bias in the reporting of these investigations according to a recent review of the research.

  • Investigators analyzed 126 epilepsy intervention trials, comparing two reporting periods: 2008 to 2011 and 2012 to 2015.
  • Twenty five percent of the trials were not reported (31/126).
  • 72 of the 126 trials were conducted in at least one US center.
  • 56 of 72 trials (78%) met the US Food and Drug Administration’s Amendments Act requirements.
  • Researchers found that the time it took to report trial results had become shorter over time, when comparing 2008-2011 to 2012-2015.
  • However, only a third of the trials (19/56) reported their results within the FDA’s mandated one-year time frame.
