Figure 1.

Kaplan–Meier curves of time to clearance of type-specific oral human papillomavirus (HPV) infections, stratified by sex. Shown is the natural history of all 180 prevalent and incident oral HPV infections (A), 68 prevalent infections (B), and 112 incident infections (of 134 total incident infections detected) that had follow-up after detection (C). Overall 12-month clearance was 70.4% in men, compared with 89.6% in women (P < .001). The median time to clearance was significantly shorter for incident versus prevalent infections (3.3 vs 8.1 months; P < .001). Log-rank P values for a comparison of time to clearance of oral HPV infections in men and women are shown.
