Variables not associated with mortality included age (AHR = 1.3, P = 0.412), gender (AHR = 1.0, P = 0.345), HT (AHR = 2.5, P = 0.126), ALT elevation at baseline (AHR = 2.4, P = 0.383), current TB status (unadjusted HR = 0.9, P = 0.807), and PMTCT attendance (unadjusted HR = 0.9, P = 0.184). This evidence concerns the gene GPT and tuberculosis.
