Figure 1a. Estimated rates of intercourse initiation among virginity pledgers and non-pledgers. The leftmost bar shows estimates for non-pledgers based on a model that is adjusted with covariates only. The middle bar shows estimates for non-pledgers from a model that is adjusted with covariates and uses propensity scores to weight nonpledgers to match pledgers.
Figure 1b. Estimated rates of less than consistent condom use among virginity pledgers and non-pledgers. The leftmost bar shows estimates for non-pledgers based on a model that is adjusted with covariates only. The middle bar shows estimates for non-pledgers from a model that is adjusted with covariates and uses propensity scores to weight nonpledgers to match pledgers.
