After multivariate logistic regression analysis, five out of nine variables remained statistically significant, which were age (OR, 3.017, CI, 1.121–8.125, P = 0.029), operation time (OR, 1.953, CI, 1.182–3.225, P = 0.009), diabetes (OR, 7.453, CI, 3.422–16.230, P < 0.001), WBC (OR, 4.573, CI, 2.257–9.266, P < 0.001), HGB (OR, 0.327, CI, 0.161–0.662, P = 0.002). This evidence concerns the gene CYGB and diabetes mellitus.
