  1. aDue to missing CD4+ lymphocyte values in 37 women, 525 women were included in multivariate models
  2. bAll adjusted models included individual high-risk HPV type, age, CD4+ lymphocyte count at HPV test, and presence of more than one high risk HPV types. CD4+ lymphocyte count and presence of more than one high-risk HPV types remained statistically significant. Age was not statistically significant in multivariate models
  3. cp value significant at Bonferroni threshold (0.004) for correction of multiple comparisons
  4. Abbreviations used
  5. CI: confidence interval
  6. PR: prevalence ratio
  7. aPR: adjusted prevalence ratio
