Five-year excess hazard ratios (EHRs) in relation to tumor high-risk human papillomavirus (hrHPV) status by age at cancer diagnosis and International Federation of Gynecology and Obstetrics (FIGO) stage.

(A) By age at cancer diagnosis; (B) by FIGO stage. The reference groups are hrHPV-negative cases in the corresponding age group (A) and FIGO stage (B). In (A), EHRs were adjusted for age at cancer diagnosis as a spline term with 3 degrees of freedom, time since cancer diagnosis in 1-year bands, FIGO stage, and education. In (B), EHRs were adjusted for age at cancer diagnosis as a spline term with 3 degrees of freedom, time since cancer diagnosis in 1-year bands, and education. No estimates for women with age at cancer diagnosis under 30 years were included in (A) due to insufficient number of events. Estimates for women diagnosed at stage IA in (B) were truncated for display purposes.
