Hazard ratios for the incident detection of oncogenic HPV infection as estimated using a Wei Lin Weissfeld (WLW) Model^*

CD4 T-cell count, cells per mm3	HIV RNA, copies per mL	Hazard Ratio (95% CI)
>500	<4000	1.61(1.23,2.10)
	4001–20000	2.03(1.39,2.97)
	20001–100000	3.06(1.96,4.76)
	>100000	3.40(1.82,6.32)
200–500	<4000	2.58(2.02,3.30)
	4001–20000	3.15(2.37,4.18)
	20001–100000	4.02(3.02,5.35)
	>100000	4.77(3.47,6.56)
<200	<4000	4.55(3.33,6.21)
	4001–20000	5.10(3.70,7.03)
	20001–100000	4.55(3.38,6.12)
	>100000	4.87(3.75,6.34)

^*HIV-negative women were the reference group. The WLW model (model (1.10)) adjusted for the same variables reported in Figure 1.
