Table 3 Comparison of laboratory parameters between groups. HbA1c: glycated hemoglobin; FBG: fasting blood glucose; TC: total cholesterol; TG: triglycerides; LDL-C: Low-density lipoprotein cholesterol; HDL-C: High-density lipoprotein cholesterol; INR: international normalized ratio; TNF-α: tumor necrosis factor alpha, MDA: malondialdehyde; S.D: standard deviation. (#): unpaired t test; (##): paired t test; (@) Mann Whitney U test; (”): Wilcoxon signed ranks test. P value 1 is for comparison variables between the two groups; P value 2 is for comparison variables in one group; *P value < 0.05 is considered significant.
