Forest plot depicting the differences in abundance estimates (blue dot) and 95% confidence intervals (CIs) (solid red line) among sexual risk behavior groups of each of the taxonomic groups with an abundance of ≥2% across the entire sequence library.

<p>A relative ratio of 1 (dotted vertical line) signifies that both comparison groups have the same mean abundance. If the solid red line for sexual risk behavior group comparisons does not overlap with a relative ratio of 1, a statistically significant difference between the two comparison groups is supported.
