  1. Data are presented as the mean and standard deviation (SD). P-values are based on a t-test or Wilcoxon rank sum test. Statistically significant (p < 0.05) values are presented in bold. DOS: day of surgery; CRP: C-reactive protein; CCl: creatinine-clearance; WBC: white blood cell count; BUN: blood urea nitrogen.
