Probability to be high-risk (HR) HPV infected at first screen in multivariate analysis by logistic regression for odds ratio (OR) and Poisson regression for relative risk (RR)

	Probability to be HR HPV at first screen: OR and RR, (95% Confidence Interval) (95% CI)	Multivariate analysis
Age
for each increment of 5 years	OR=0.81 (95% CI: 0.74–0.88)	p<0.0001
	RR=0.89 (95% CI: 0.85–0.93)	p<0.0001
CD4+ Lymphocyte cells count/µL
for each increase of 100 cells	OR=0.82 (95% CI: 0.76–0.89)	p<0.0001
	RR=0.89 (95% CI: 0.85–0.93)	p<0.0001
