Receiver operating characteristic (ROC) curves for ability of pathology to classify cases as demented or non-demented created using the probabilities obtained in the binary regression models. (A) Cortical Lewy body (LB) scores alone (area under the curve = 0.83, 95% CI = 0.70–0.97, P = 0.001); (B) tau stages alone (area under the curve = 0.82, 95% CI = 0.70–0.93, P = 0.0001); (C) cortical amyloid-β (A-β) scores alone (area under the curve = 0.83, 95% CI = 0.69–0.97, P = 0.001); and (D) all three pathologies in combination (area under the curve = 0.95, 95% CI = 0.88–1.00, P = 0.000003). AD = Alzheimer’s disease.
