  • SD indicates standard deviation.

  • * The P value is derived from a Pearson correlation coefficient if the behavioral/partner characteristic variable is continuous and from a t test or analysis of variance procedure if the behavioral/partner characteristic variable is categorical.

  • These variables were assessed during the 6 months before testing positive for HPV.

  • Self-report of risky sexual behaviors while using alcohol or illicit drugs, measured using a 9-point scale.

  • § Assessed for main sexual partner.
