NF, normal flora group; Mild AV, mild aerobic vaginitis; Moderate AV, moderate aerobic vaginitis group. The demographic characteristics were compared among the three groups using the non-parametric Kruskal–Wallis test followed by Mann–Whitney U test and Chi-square test (*p-value < 0.05 indicates statistical significance). No. indicates number. The vaginal pH was measured in 110 subjects. a represents the total number of subjects for which pH was obtained/total number of subjects in each group.
