Prevalence of VVC/RVVC and distribution of lifetime/annual frequencies of infection. a Lifetime history of VVC in participating women (n = 284, pie chart) was assessed by a self-reported survey. Total VVC episodes in respondents with disease history were further stratified by lifetime frequencies (n = 204, bar chart). b Respondents with previous VVC episodes were classified by annual frequencies (n = 202, pie chart), and those with annual frequencies of > 3 VVC episodes were further stratified by age (n = 70, bar chart). The percentage in each section indicates the proportion of women among those who reported answers to each parameter. Data were analyzed by Fisher’s exact test for binomial proportions comparing two populations of women categorized by the dashed lines. NS, not significant
