IL27 and diabetes mellitus: We explored the correlation between sirtuin 1 (Table S1), IL-27 (Table S2), and visfatin (Table S3) levels with known CV risk factors (duration of diabetes, HbA1c, BMI, lipid parameters), thyroid parameters (TSH, fT4, fT3, anti-TPO, anti-TG, thyroid volume), and selected CV parameters (cIMT thickness, QTc interval, resting HR, echocardiographic parameters).
