From: Heterogeneity of odorant identification impairment in patients with Alzheimer’s Disease
ROC curves of “cognitive” and “non-cognitive” OSIT-J subsets. Red line and blue line indicate the “cognitive subset” and “non-cognitive subset”, respectively. (a) ROC curves to discriminate AD vs (aMCI + Normal). The AUCs of “cognitive subset” and “non-cognitive subset” were 0.758 and 0.617, respectively. The difference was significant (p = 0.008). (b) ROC curves to discriminate (AD + aMCI) vs Normal. The AUCs of “cognitive subset” and “non-cognitive subset” were 0.879 and 0.654, respectively. The difference was significant (p = 0.005). Abbreviations: ROC, receiver operating characteristic; AUC, area under the curve; OSIT-J, Odour Stick Identification Test for Japanese; AD, Alzheimer’s disease; aMCI, amnestic mild cognitive impairment.
