  1. Note: *Covariate data were missing for some women and the total observations therefore sum to less than 550 for certain univariate analyses. VL: viral load per cell, α5 HPV species is HPV-51; α6 HPV species is HPV-56; α7 HPV species are HPV-18, -39, -45 and -59; α9 HPV species are HPV-16, -31, -33, -35, -52 and -58.
