Sensitivity, specificity, positive predictive value, and negative predictive value of various clinical features for distinguishing patients with dementia with Lewy bodies (DLB) (“pure” and “mixed” DLB–Alzheimer’s disease cases) from patients without DLB

* Seven out of the nine pure DLB cases, five out of the nine DLB–Alzheimer’s disease cases, and 40 out of the 76 non-DLB cases were exposed to neuroleptics.
CDLB = Consortium on DLB.
