a Alpha diversity by PD_whole_tree was lower in Normal women than in the other groups of gynecological infections and was significantly lower in normal women than in BV positive women(P<0.05). b Women in pregnancy (from ≥40 days gestation to parturition) had significant lower PD_whole_tree than those with childbearing. c Women in pregnancy had significant lower PD_whole_tree than those in follicular phase. d Means and 95% intervals of 10 genus-level relative abundances that had no significant difference among groups by childbearing history and menstrual cycle according to both ANOVA and nonparametric kruskal_wallis with Bonferroni correction. But the relative abundances of Gardnerella, Streptococcus, and an order-level relative abundance of Lactobacillales (NA (Firmcutes)) were significantly different among the 5 groups of gynecological infections. In a, b and c, the boxes are interquartile range (IQR); median values are the bands within the boxes; the line terminals outside the boxes are upper and lower endpoint of the data; crosses are outliers. In d, the lines are 95% intervals of genus-level relative abundance; mean values are icons in the middle of the 95% interval lines
