—: the multivariate analysis of intraoperative blood loss was not performed in this study because of its corresponding relationship with intraoperative blood transfusion. Missing values: 3 diabetes mellitus patients and 2 hypertension patients were missing. OR: odds ratio; CI: confidence interval; ORadj: adjusted ORs presented with 95% CI.
