Estimated false discovery rate at different threshold p-values for comparisons of three groups. The x-axis represents different p-value cutoffs (0.00–0.10) to determine differential expression, and the y-axis represents the estimated false discovery rate (FDR) expected for each cutoff. The color key to differentiate the three possible null hypotheses involving pair-wise combinations of all of the three groups is shown in the legend.
