Receiver operating characteristic curves for the clinical functional outcome. Predictive values of ALC, ALB and PNI for the poor outcome. Area under the curve 0.71(95% CI, 0.63–0.79) for ALC, 0.69 (95% CI, 0.59–0.79) for ALB and 0.75(95% CI, 0.66–0.84) for PNI. ALC: absolute lymphocyte count, ALB: albumin concentration and PNI: prognostic nutritional index
