INS and chronic kidney disease: Male sex (HR, 1.98; 95% CI 1.10–3.57; p = 0.024), hypertension (HR, 1.66; 95% CI 1.03–2.70; p = 0.039), and poor glycemic control, as reflected by the glycated hemoglobin level (HR, 1.27; 95% CI 1.09–1.48; p = 0.002), were all significantly associated with MI (Additional file 2: Table S2), whereas age (HR, 1.05; 95% CI 1.00–1.11; p = 0.039), chronic kidney disease (HR, 4.29; 95% CI 1.41–13.04; p = 0.010), and insulin use (HR, 2.54; 95% CI 1.01–6.38; p = 0.047) were associated with all-cause mortality (Additional file 2: Table S3).
