Summary of study outcomes by cut-off values at admission. In-hospital mortality. If the patient’s eGFR (ml/min/1.73 m2) at admission was less than 25.96 was more likely to die (Fig. 2a). Discharge home. Above 36.64 eGFR value, the outcome was discharge home, rather than in-hospital mortality, transfer to other ward or leave against medical advice (Fig. 2b). Need for RBC transfusion. Worse eGFR than 49.61 predicts RBC transfusion (Fig. 2c).
