Data are given as mean ± standard deviation or total number (percentage). values are computed for the comparison between groups with and without predisposing factors; IHD: ischemic heart disease; COPD: chronic obstructive pulmonary disease; DVT: deep vein thrombosis; PVD: peripheral vascular disease; †abdominal surgery includes laparotomy, appendectomy, and laparoscopic surgery.
