Figure 4

Decision curve analysis (DCA) for coronary heart disease (CHD) prediction in men and women with and without diabetes. Horizontal dotted lines are net benefit of treating no participants, assuming that all would not develop CHD; gray line is net benefit of treating all participants similarly, assuming that all would develop CHD; net benefit of treating participants based on Suita score (TC) is black line and those based on New risk prediction model 1 (orange), Suita score (TC) new coefficients (blue lines), New risk prediction model 2 (light blue lines), and New risk prediction model 3 (light pink lines)are also shown. Dotted lines are 95% confidential intervals. (New risk prediction model 1: Suita score (TC) + new covariates*, New risk prediction model 2: Suita score (TC) new coefficients + new covariates*, New risk prediction model 3: Suita score (TC) new coefficients + new covariates 2**, *new covariates: Waist circumference (≥85 cm) in men and proteinuria (≥1+) in women were included, **new covariates 2: Triglyceride, drug of diabetes, hypertension, and dyslipidemia, waist circumference (≥85 cm), and proteinuria (≥+−) in men, and triglyceride, drug of diabetes, hypertension, and dyslipidemia, waist circumference (≥90 cm), and proteinuria (≥1+) in women were included.
