Reference group for analysis was non-MCI group. Model I: Model χ2 test, p < 0.0001; The Hosmer–Lemeshow test, p = 0.12; Percentage of correct classifications = 87.4%. Model II: Model χ2 test, p < 0.0001; The Hosmer–Lemeshow test, p = 0.84; Percentage of correct classifications = 84.5%. Model III: Model χ2 test, p = 0.002; The Hosmer–Lemeshow test, p = 0.02; Percentage of correct classifications = 59.2%. CI, confidence interval; WR, word recognition; TMT-A, Trail Making Test A version; TMT-B, Trail Making Test B version; SDST, Symbol Digit Substitution Task; TDAS, Touch Panel-type Dementia Assessment Scale; GDS, Geriatric Depression Scale-15.
