Mean FDR difference [%] between each differential abundance method and its GMPR normalised version for tooth dataset in the scenario with simulated DA features.

Different percentages (P) of simulated DA features are on rows, while different sample size (SS) values are on columns. Numbers at the beginning of each row correspond to the FDR values obtained with default normalization, while the symbol (*) identifies that the Wilcoxon unpaired statistical test is significant.
