| Incident genital HPV infectiona | 12-month cumulative incidence, % (95% CI) | 24-month cumulative incidence, % (95% CI) | Median time from incident genital HPV infection to GW detection, months (95% CI) |
| Any GW | 1.7 (1.2–2.3)b | 5.2 (4.1–6.4)b | 17.1 (12.4–19.3)c |
| Any HPV type | 2.4 (1.6–3.3) | 6.8 (5.0.-8.6) | 12.6 (12.1–18.4) |
| Nononcogenic HPV types only | 4.1 (2.2–6.0) | 6.7 (3.9–9.4) | 7.6 (6.2–12.2) |
| Oncogenic HPV types only | 1.8 (.0–3.5) | 5.5 (.9–9.9) | 19.4 (6.2–23.5) |
| Both nononcogenic and oncogenic HPV types | 1.5 (.5–2.4) | 6.8 (4.3–9.3) | 18.8 (12.7–23.9) |
| HPV 6/11d | 5.8 (2.6–9.0) | 14.6 (7.5–21.1) | 12.2 (6.2–18.9) |
| HPV 6/11 only | 8.9 (.0–18.1) | 13.7 (.0–25.8) | 6.2 (5.6–24.2) |
| HPV 6/11 and other HPV types | 5.2 (1.8–8.5) | 14.5 (6.7–21.7) | 13.3 (6.3–19.6) |
| HPV types other than 6/11 | 2.5 (1.5–3.4) | 5.5 (3.8–7.3) | 18.2 (12.4–23.6) |
