Comparison of the number of significant features for an FDR threshold of 0.05, 0.1, or 0.2. The unshaded bar indicates the number of true discoveries, and the shaded bar indicates the number of false discoveries. Results were averaged over 100 replicates. Left panels: all features were considered; Right panels: only non-normal features (Shapiro-Wilk test p-value <0.01 for at least one of the two groups) were considered
