Cox proportional hazards using unadjusted (univariate) and adjusted (multivariate) analyses to assess the effects of covariates on the rate of CD4+ T cell recovery, defined as time for CD4+ T-cell count increase to ≥350 cells/μL during cART.

Abbreviations: cART, combination antiretroviral therapy; HR, hazard ratio; CI, confidence intervals; Ref, reference.
a covariates with P values < .25 were included in the adjusted analysis. The rate of CD4+ T cell recovery was also adjusted for baseline HIV-1 RNA because it is known to be an important predictor of immunologic recovery.
