Appendix EAnalyses of Potential Publication Bias

We used Comprehensive Meta-Analysis Version 2 (Borenstein M, Hedges L, Higgins J, Rothstein H. Comprehensive Meta-analysis Version 2, Biostat, Englewood NJ [2005]) to test for potential publication bias for the outcomes described below. Figures E-1 to E-5 show the resulting funnel plot for each outcome. Note that there is no asymmetry in any of the plots.

Endometrial Cancer Incidence

We also computed Begg and Mazumdar's correlation test for publication bias for each cancer incidence (Table E-1). None of the correlations were significant although breast cancer incidence was marginal.

Overall, there was no evidence of publication bias in the meta-analyses.
