  1. n.s. = not selected by stepwise regression
  2. Stepwise regression (backward selection) of HSV-2 serostatus on selected covariables. For dichotomous covariables the β coefficients are the natural logarithms of the adjusted odds ratios of the association between the covariable and HSV-2 seropositivity. Analyses adjusting for age at first sex (firstsex) as a covariable exclude individuals without sex partners.
