Principal component analysis (log2-transformed) of the 13 most abundant genera. The first two components are plotted (PC1: 32.2% variance; PC2: 18.1% variance). Individuals are represented by points. The length of the vectors represents the effect of each component on the status. a The two colors represent the test resutls of the Amsel criteria. Red color means A+, and blue color means A–. b The three colors represent the three test restuls of the Nugent score test. Red color means N+, yellow color means N*, and blue color means N–.
