Forest plot of the association between baseline HPV serostatus and type-specific HPV incident detection by HIV status for A HPV-16 and B HPV-18. †Indicates estimates that are adjusted for confounders; NA = Not available. Participants included in the publication by Kelly et al. [40] were restricted to women living with HIV. The other publications reported separate estimates of measures of association by HIV status. CD4 cell counts of HIV positive individuals were reported in varying format by publications (threshold, median). All 5 publications adjusted for the baseline CD4 cell counts in the calculation of estimates in either main analysis or sensitivity analysis. Only two publications reported information regarding treatment status of HIV positive individuals at baseline and/or throughout the study period
