ROC curves showing the performance of the Diabetes Risk Score in predicting diabetes in the 1987 and 1992 cohorts; follow-up of both cohorts continued until the end of 1997. ROC curves showing the performance of the Diabetes Risk Score in predicting diabetes in the 1987 and 1992 cohorts; follow-up of both cohorts continued until the end of 1997. The area under the 1987 curve was 0.85 and the area under the 1992 curve was 0.87. For cut point Diabetes Risk Score ≥9 (black marker), sensitivity was 0.78 (95% CI 0.71–0.84) and 0.81 (0.69–0.89), specificity was 0.77 (0.76–0.79) and 0.76 (0.74–0.77), PPV was 0.13 (0.11–0.15) and 0.05 (0.04–0.06), and negative predictive value was 0.99 (0.98–0.99) and 0.996 (0.993–0.998) in the 1987 and 1992 cohorts, respectively.
