CD4 and coinfection: The OR obtained from the logistic regression yielded a statistically significant association between CD4 < 200 μl and multiple HPV co-infections (OR: 3.7; 95 % CI: 1.2–12.1; p = 0.03) but a non-significant association between CD4 count ≥350 cells/μl and multiple HPV infections (OR: 0.7; 95 % CI: 0.3–2.0; p = 0.5).
