Predictors of mortality by Cox proportional hazards regression. 1) Patient characteristics at retreatment initiation, stratified by gender. 2) Time-Dependent analysis of ART exposure and CD4 count during retreatment.

Factor	Hazard Ratio (95% CI)	p-value
Characteristics at Retreatment Initiation
Age (5 year increment)	1.1 (0.9–1.3)	0.54
Weight (5 pound increment)	0.7 (0.6–0.9)	0.001
Hemoglobin (1 gram/deciliter increment)	0.5 (0.4–0.8)	<0.001
Initial CD4 Count (50 cell/mm increment)	1.0 (1.0–1.1)	0.35
ART Exposure and CD4 Count During Retreatment
ART Exposure	0.6 (0.1–2.7)	0.48
CD4 Count (50 cell/mm increment)	0.7 (0.6–0.9)	0.004
