The results of univariate analysis showed that the differences in age, diabetes mellitus, operation time, blood transfusion, internal fixation, postoperative NLR and postoperative CRP/ALB ratio were statistically significant when comparing the two groups (P < 0.05); and the differences in comparison of gender, BMI, hypertension, coronary artery disease, history of smoking, history of alcohol consumption, and surgical site were not significant (P > 0.05), as shown in Table 1 and Figure 2. Here, ALB is linked to hypertensive disorder.
