Predictors of species 7 and 9-specific persistent* oral HPV infections in GEE modeling1 run in a univariate mode and as adjusted for significant covariates.

Species 7 HPV genotypes: 18, 39, 45, 59, 68, 70, and 85. Species 9 HPV genotypes: 16, 31, 33, 35, 52, 58, and 67; *Binary outcome (persistent/not persistent), as defined by persistence of the two original HPV species (same genotype) during the follow-up;1Results obtained from GEE with logit link for binary outcomes clustered by woman-ID, 95% CI calculated by robust estimation; @adjusted for age and all significant (and borderline) univariates in the model.
