Table 3.
Cumulative incidence and risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in association with varied HPV viral load among normal women or women with CIN1 at baseline, stratified by combinations of HPV viral load at baseline and follow-up.
| HPV Viral Load | No. CIN2+/No. women | Cumulative Incidence of CIN2+ | aHR‡ | 95% CI |
|---|---|---|---|---|
| Repeat Negative | 2/1199 | 0.2% | 1 | - |
| Single/ Repeat Low load† | 0/124 | - | - | - |
| Single Moderate/ High load at baseline | 3/100 | 3.0% | 19.1 | 3.2–114.5 |
| Single Moderate/ High load at follow up | 1/97 | 1.0% | 6.8 | 0.6–74.8 |
| Repeat Moderate/ High load† | 11/38 | 29.0% | 188.8 | 41.2–864.1 |
Viral load categories represent the maximum measured viral load for a given woman for either time point.
aHR=Hazard Ratio adjusted for age, number of full-term births and number of lifetime sexual partners.
