Risk of surgical site infection in different risk index categories. The width of each bar is proportional to the sample size in that particular group; a) shows the traditional National Nosocomial Infection Surveillance (NNIS) risk index categories; b) shows a modified NNIS risk index with chronic disease score >5,000 substituted for ASA >3; c) shows a modified NNIS risk index, incorporating both chronic disease score >5,000 and the traditional NNIS risk index categories. In each group,
