Percent change in vaginal pulse amplitude (VPA) as predicted by C-reactive protein and frequency of partnered sexual activity.

Note: In analyses, sexual frequency data consisted of six ordinal bins ranging from “never/less than monthly” to “more than daily.” For visualization purposes, sexual frequency is displayed as a binary between those reporting partnered activity at a frequency of weekly or less versus those reporting partnered activity more than once per week.
