Fig 4. Median pAUCs in relation to the number of modalities analysed in the different modalities scenario.

Each line corresponds to a specific method. The x axis represents the number of modalities analysed, and the y axis the median pAUCs. Circles suggest that the observed differences from the best method were not statistically significant at level ≤ 0.05. A) Only genes which exhibited the same behaviour across all datasets were taken into account. In this experiment only the integrative approaches were evaluated. CP and omicsNPC^Fisher were the best method in all cases. B) All genes were considered in this analysis. omicsNPC^Tippett, omicsNPC^Fisher, CP and Benjamini achieved better performance than other methods.
