Elevated urinary C\u2010peptide to creatinine ratio (UCPCR) as an alternative measurement is shown to be related to insulin secretion dysfunction; however, data regarding UCPCR predictive value for CAD in diabetes mellitus (DM) are scarce. Therefore, we aimed to assess the UCPCR association with CAD in type 1 DM (T1DM) patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>279 patients previously diagnosed with T1DM included and categorized into two groups of CAD (<jats:italic>n<\/jats:italic>\u00a0=\u00a084) and without\u2010CAD (<jats:italic>n<\/jats:italic>\u00a0=\u00a0195). Furthermore, each group was divided into obese (body mass index (BMI)\u2009\u2265\u200930) and non\u2010obese (BMI\u2009&lt;\u200930) groups. Four models utilizing the binary logistic regression were designed to evaluate the role of UCPCR in CAD adjusted for well\u2010known risk factors and mediators.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Median level of UCPCR was higher in CAD group compared to non\u2010CAD group (0.07 vs. 0.04, respectively). Also, the well\u2010acknowledged risk factors including being active smoker, hypertension, duration of diabetes, and body mass index (BMI) as well as higher levels of haemoglobin A1C (HbA1C), total cholesterol (TC), low\u2010density lipoprotein (LDL) and estimated glomeruli filtration rate (e\u2010GFR) had more significant pervasiveness in CAD patients. Based on multiple adjustments by logistic regression, UCPCR was a strong risk factor of CAD among T1DM patients independent of hypertension, demographic variables (gender, age, smoking, alcohol consumption), diabetes\u2010related factors (diabetes duration, FBS, HbA1C), lipid profile (TC, LDL, HDL, TG) and renal\u2010related indicators (creatinine, e\u2010GFR, albuminuria, uric acid) in both
