Longitudinal Lf concentration (μg/ml) in 51 women seen while non-pregnant (at end assessment) and while pregnant (at ANC1 and/or ANC2). Lines join the measurements on the same woman at the three time points. Panels and colors indicate the non-pregnant Lf quartile: low, intermediate and high levels at the first assessment time. Closed circle: BV or T. vaginalis infection at the time of visit; open circle: no infection. Data are offset slightly for clarity. Shaded boxplots are included, showing the full cohort range (median, IQR, min, max)
