^aIncident type-specific high-risk HPV detection was defined as the first DNA-positive sample for a HPV type not detected at enrollment; samples after each type-specific first positive detection were considered censored.

^b246 women contributed 804 women-types to the seropositive analysis.

^cAdjusted odds ratio adjusted for all other variables in the table

^dThere was a borderline statistically significant linear categorical dose-response relationship between increasing BMI categories and likelihood of hrHPV detection (p=0.06 by trend test).
