CD4 and infection: However, in the multivariate analysis only CD4 cells > 500/mmc remained an independent predictor of HPV clearance (aHR 2.44, 95% CI 1.15–5.18, p = 0.021), while infections with HR-HPV genotypes showed only a nearly significant trend towards a reduced probability of clearance (aHR 0.56, 95% CI 0.31–1.01, p = 0.054).
