1. Receiver under the operator characteristic (ROC) curve for the test accuracy of the final risk score in the entire external validation sample (c statistic=0.84, 95% CI 0.83 to 0.85), ignoring clustering of patients within practices.
Receiver under the operator characteristic (ROC) curve for the test accuracy of the final risk score in the entire external validation sample (c statistic=0.84, 95% CI 0.83 to 0.85), ignoring clustering of patients within practices. Each point on the graph represents the performance (sensitivity and specificity) of the risk score at specific thresholds.
