Schwegler et al. Nutritional risk is a clinical predictor of postoperative mortality and morbidity in surgery for colorectal cancer. Br J Surg 2010;97:92-7.
Based on the NRS-2002, there was a significant difference in postoperative complication rate between patients at nutritional risk and those not at risk (62 versus 39.8 per cent; P = 0.004) but not if Reilly's NRS was used (58 versus 44.1 per cent; P = 0.086).
Nutritional risk was identified as an independent predictor of postoperative complications (odds ratio 2.79; P = 0.002).
