Table 2 Risk factors for poor survival and loss to follow-up during the first year of cART, hazard ratios (HR), univariate and multivariate analysis

From: Improved antiretroviral treatment outcome in a rural African setting is associated with cART initiation at higher CD4 cell counts and better general health condition
