Figure 2.

Alpha-diversity indices vary by sample-type and age. Violin plots show within-group distributions of values across sample-types (A), age quartiles (B), cholesteatoma diagnosis (C), or quinolone use (D). Open blue circles indicate individual samples while filled black circles designate group means. Results of linear mixed-effects tests are indicated above violin plots. Red lines/symbols indicate p-values across all four groups. Blue lines/symbols indicate p-values for pairwise comparisons with false discovery rate correction.
