Additionally, a meta-analysis of six studies evaluated the significantly higher serum vaspin levels in obese (n = 1826, vaspin level higher by 0.52 ng/mL, 95% confidence interval [CI]: 0.10–0.93, p = 0.02) and T2DM patients (n = 1570, vaspin level higher by 0.36 ng/mL, 95% CI: 0.23–0.49, p < 0.00001) that in non-obese healthy controls [6]. Here, SERPINA12 is linked to type 2 diabetes mellitus.
