BV status and vaginal pH in the SOC and intervention group. a BV status was determined by Nugent scoring at screening, and one, three and five months post-treatment. Nugent Score 0–3 = BV negative (white area); 4–6 = BV intermediate (yellow) and 7–10 = BV positive (orange). b Vaginal pH was measured using color-fixed indicator strips one, three and five months post-treatment. A vaginal pH < 4.5 (white area) is seen as protective. Each participant is represented by a symbol-coded dot, and the summaries show median and interquartile range
