Beta diversity plot based on Bray–Curtis dissimilarity (a) and pairwise comparison of Bray–Curtis dissimilarity for the three different dressings (b). a Each different color denotes each participant. The plots from the same participant are connected by lines. b The P value outside the box is the result of the Friedman test, whereas the P value inside the box is calculated by the Nemenyi post-hoc pairwise test. ^*P < 0.05, ^**P < 0.01. PC, principal coordinate; A, acrylic adhesive; U, urethane adhesive; S, silicone adhesive. The blue box in (b), A vs. U; the yellow box, A vs. S; the gray box, U vs. S
