Differential Effect of Vaginal Microbiota on Spontaneous Preterm Birth among Chinese Pregnant Women

Figure 1

The alpha and beta diversity metrics of vaginal microbiota between the sPTB and controls. The violin plots were applied to illustrate the alpha diversity metrics (a–d) between the two groups. values in the violin plots were evaluated based on the Wilcoxon test. PCoA plots were applied to illustrate the beta diversity metrics (e–h) between the two groups, and values in the plots were evaluated based on the Adonis analysis. The percentage on axis label was the proportion of variance explained by that axis.
