Adjusted hazard ratios and associated 95% confidence intervals for mortality stratified by blood transfusion status. ^aModel #1 (clinical model) adjusted for hemoglobin concentration, cardiopulmonary illness status, and renal function (estimated glomerular filtration rate <30 mL/min/1.73 m²; yes or no). ^bModel #2 (fully adjusted model) adjusted for age, gender, CD4 cell count, hemoglobin concentration, C-reactive protein concentration, renal function (eGFR <30; yes or no), mycobacterial blood culture result, and primary clinical diagnosis category. The comparator group for all analyses was those who did not receive a blood transfusion.
