Proportion of ImaGO term enrichment. For each threshold τ (x-axis), we depict the proportion of ImaGO terms for which we observer a smaller p-value in cMoG than in MoG (y-axis). The threshold τ discards ImaGO terms, where the difference in the log of the p-value of cMoG and MoG in smaller then τ. As can be observed, the proportion is higher then 0.5 for all τ values, which indicates an advantage of cMoG. Furthermore, the proportion has an increasing tendency for higher τ values.
