In multivariable models, risk factors for death in adult VL patients were: anaemia (odds ratio (OR) 4.46 (95% CI 1.58–12.6) for Hb <6g/dL compared with ≥9g/dL), nutritional status (OR 4.84 (2.09–11.2) for BMI <13 kg/m2 compared with ≥16 kg/m2), weakness (OR 4.20 (1.82–9.73) for collapsed compared with normal weakness), jaundice (OR 3.41 (1.17–9.95)), and oedema/ascites (OR 4.86 (1.67–14.1)). The gene discussed is GSTM1; the disease is anemia (phenotype).
