Fig. 3. Alpha diversity in control skin, AK and SCC swabs from immunosuppressed and immunocompetent individuals.

Tukey style box plots showing genus diversity across sample types for organ transplant recipient and immunocompetent cohorts. Diversity is represented by three separate measures of alpha diversity; Chao1 (richness), Shannon (diversity) and Simpson (evenness). Bars indicate median ± 1.5 × interquartile range and the mean diversity for each sample type is indicated by the black dot. Significant differences between sample types are indicated by *p ≤ 0.05, **p ≤ 0.01 and ***p ≤ 0.001 as calculated via Dunn’s multiple comparisons test.
