  1. Data presented as mean (standard deviation). Adjustment is made for age, sex, and Mini-Mental State Examination score. The AD group is considered the reference group. The dementia category of the original Charlson scoring is not reported here because the whole study population is dementia patients in our study. Statistically significant ORs (P≤0.05) in bold. AD, Alzheimer’s disease; CI, confidence interval; DLB, dementia with Lewy bodies; OR, odds ratio. aChi-square statistics. bBinary logistic regression model.
