Tests for Publication Bias
Because of the potential for 'publication bias phenomenon', in which authors/sponsors may differentially or preferentially disclose trials results or publish non-damaging studies in scientific journals, thus leading to potentially biased results, we conducted several tests of publication bias. However, as noted in meta-analysis references (by Egger and by Rothman, see left column), these tests may be underpowered and unable to detect publication or reporting bias even when such bias exists. Thus, results of tests for publication biases are only suggestive, but not conclusive.
