However, IL-6 levels in obese T2DM patients (BMI ≥ 30 kg/m2) were higher than lean (BMI < 25 kg/m2) and overweight (25 ≤ BMI < 30 kg/m2) patients (tendency), although the linear regression analysis has not showed an independent association between these parameters. Here, IL6 is linked to type 2 diabetes mellitus.
