The table shows the Spearman's rank correlations between each sexual network statistic and the prevalence of HIV and HSV-2. The table also shows the predictors of HIV and HSV-2 prevalences as determined through multiple regression analyses on model simulations. The sexual network predictors were investigated through two model types, Concurrency Class model and Number of Partners Class model.
AIC, Akaike's information criterion; CI, confidence interval.
