Adjusted hazard ratios for death used in the two prognostic models: CD4 model and total lymphocyte count/haemoglobin (TLC/Hb) model.

≥1200		0.53 (0.43–0.65)
Categories of anaemia†
Severe (reference)		1

Results from Weibull models adjusted for all variables shown, based on 10,331 patients remaining in care, with missing values imputed.

^*Less advanced=WHO stage I or II, advanced=WHO stage III or IV

^†Severe=haemoglobin <8 g/dL, moderate=haemoglobin 8–10 g/dL in females and 8–11 g/dL in males, mild=haemoglobin 10–12 g/dL in females and 11–13 g/dL in males; none=haemoglobin >12 g/dL in females and >13 g/dL in males
