The median abundance of the most common genera is shown for the peritoneal dialysis cohort, the kidney transplant cohort, and the living donor/healthy control cohort. P values shown were calculated using the Wilcoxon rank-sum test between groups. Adjusted P values were calculated using Benjamini–Hochberg adjustment. P values with NA were unable to be calculated because the abundances were 0 in both groups. PD, peritoneal dialysis; KTx, kidney transplant; HC, healthy control; NA, not available.

^aP value or adjusted P value <0.10.
