Participant characteristics associated with mortality, the HIV Outpatient Study, 1995–2016 (N = 1645).

Participant characteristics	Univariate Cox proportional hazards analyses HR (95% CI)	P
Baseline age, per 10 y	1.83 (1.54–2.17)	<.001
Public insurance at baseline	2.72 (1.89–3.93)	<.001
PWID HIV risk activity	6.13 (3.71–10.13)	<.001
Heterosexual HIV risk activity	2.46 (1.63–3.71)	<.001
CD4+ cell count, pre cART, per 100 cells/mm3	0.80 (0.73–0.89)	<.001
Most recent log10 viral load, per 1 log copies/mL∗	1.63 (1.43–1.85)	<.001
Viremia log10 copy-years, copies/mL times years∗	1.69 (1.46–1.97)	<.001
%PY with viral load >200 copies/mL, per 10% increment∗	1.22 (1.16–1.28)	<.001
%PY with viral load >50 copies/mL, per 10% increment∗	1.20 (1.14–1.27)	<.001

Characteristics are summarized at baseline (defined as the date 6 months after cART initiation), unless otherwise indicated. %PY = percent person-years, cART = combination antiretroviral therapy, CI = confidence interval, HR = hazard ratio, PWID = persons who inject drugs.
