| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
AMDF was examined for its ability to discriminate between subjects according to the decision to change treatment at baseline. In terms of z scores by Mann-Whitney testing and ROC curves, AMDF performed better than other measures (AUC 0.730 (0.680 to 0.780)) |
