Charan Jayakaran et al. Indian Pediatr. 2011 Jun.

Abstract

51 inconclusive studies published in 14 Indian medical journals were analyzed for adequacy of power by post hoc power calculation. No study was found to be adequately powered (%80%) at small effect size, only 8 studies were adequately powered for medium effect size and 30 studies were adequately powered at large effect size.
