Relative abundance at an order level of samples. In this tree plot, most of the samples can clustered be clustered into two groups: cluster A (shaded in blue; N = 22) and cluster B (shaded in brown); N = 17). There is no enrichment of the sex or collection method between these two clusters (p = 0.11 for Collection, and p-value = 0.49 for sex; Fisher’s exact test). Sex of the subject and sample collection approach are indicated by the colored tiles below the tree, where dark green represents for cystoscopy (C), light green for voided (V), orange for female (F), blue for male (M) and pink for not defined (ND, i.e. positive controls)
