PCoA analysis of samples with Bray–Curtis analysis (beta diversity), shown along the first two principal coordinates (PC1 and PC2). Each subject is represented by paired measurements before (skyblue circles) and after (salmon diamonds) the intervention, labeled with subject IDs (1–13). The ordination illustrates within-subject trajectories and overall differences in beta diversity between pre- and post-intervention states.
