Multivariate model of risk factors for gynecological cancer for the 11,258 study subjects, 1991–2011.

aHazard ratio (HR) and confidence interval (CI) were derived from Cox proportional hazard models using attained age during follow-up as the time axis and stratification of birth cohort in 5-year calendar periods.bPAF: population attributable fraction of total cases that would be reduced if a modifiable risk factor were eliminated from the study cohort. The formula for PAF estimation is presented in Methods section. N.A.: not applied.
