  1. The majority of DM methods assigns a zero p-value to some percentage of the predictions, while only the Fisher and Stouffer MA methods do so. These percentages are higher in E. coli than in Yeast, suggesting that in the first compendium the statistical associations are stronger or more detectable due to higher statistical power
