Small-study effects (publication bias, etc.) were examined using the recently developed Doi plot [8], an approach considered to provide more robust estimates of asymmetry, i.e., small-study effects, than previously developed and recommended approaches [9].
Such frequency distributions usually exhibit one of the following three patterns: directional asymmetry, antisymmetry and fluctuating asymmetry.
