Figure 4. Comparisons of Performance Between Multivariable Logistic Regression Model.

The graphs represent the AUC (95% CI) showing the performance of diagnostic prediction for model 1, model 2, and model 3 and statistical comparisons of AUCs between the models by the DeLong test after multiple imputation, for distinguishing AD and controls in the iBEAS cohort. *p < 0.05. AD = Alzheimer disease; AUC = area under the receiver operating characteristic curve.
