Result of multivariate logistic analysis. According to the final model, the probability of anal HPV infection is plotted versus the CD4 count. In order to take account of the patients' ages, three separate lines are depicted corresponding to representative age points. The 25th percentile corresponds to an age of 34 years, the 50th percentile (median) to 42 years, and the 75th percentile to 50 years.
