Discriminative power of group-specific probes among E. coli pathotypes. The ability of probe-wise discrimination derived from ANOVA-based simultaneous inference of one-sided multiple comparisons further decreases in the E. coli pathotype level of the pathogroup tree. Single red dots mark averaged adjusted p-values of group-specific probes. The overall distribution of p-values as indicated by violin plots exhibits a general increase of p-values. The increase is influenced by a larger number of comparisons and by the close relation of the target groups.
