Table 3. Surgical characteristics and outcomes.
a Hemoglobin 1 day before surgery, b Hemoglobin 1 day after surgery, c p-values were derived via one-way ANOVA for categorical and continuous variables, and chi-square test for categoric variables
UTI: urinary tract infection; EBL: estimated blood loss; ANOVA: analysis of variance
