We also found significant positive correlations between the serum vaspin concentration and BMI (r = 0.75, P = 0.035), WHR (r = 0.79, P = 0.032), FINS (r = 0.56, P = 0.045), C-peptide (r = 0.58, P = 0.043), mass of visceral adipose (r = 0.83, P = 0.024), and HOMA-IR (r = 0.78, P = 0.033) among patients with T2DM (Table 3). Here, SERPINA12 is linked to type 2 diabetes mellitus.
