CRP and infection: On binary logistic regression analysis, deprivation (P<0.10), emergency presentation (P<0.001), peritoneal soiling (P=0.001), elevated preoperative white cell count (P<0.001), C-reactive protein (P<0.001), albumin (P<0.001) and mGPS (<0.001) were associated with increased risk of developing a postoperative infection.
