However, the number of studies that reported an adequate sequence generation evidenced a nonsignificant trend (38.6% and 77.8%, Fisher’s Exact test, p = .06) and the number of studies that reported that an independent party conducted the randomization was significantly smaller among the published studies (25.0%) than among the unpublished studies (77.8%; Fisher’s Exact test, p = .005).
