Distribution of Relative Abundance of <i>Lactobacillus</i> by Glycogen Concentration.

<p>Glycogen levels were measured in vaginal fluids collected annually from 21 women over 8–11 years. (A) The final analytic sample consisted of 177 observations with non-missing values for both glycogen and <i>Lactobacillus</i>. The distribution of <i>Lactobacillus</i> relative abundance is summarized by glycogen as a continuous variable. (B) The relative abundance of <i>Lactobacillus</i> and concentration of glycogen over time by participant. Left Y axis is relative abundance of <i>Lactobacillus</i>; right Y axis is glycogen concentration (µg/µl). X-axis is annual visit number.
