Calculated using item response theory (IRT).
Abbreviations: CCI, Charlson Comorbidity Index; GDS, Geriatric Depression Scale; IADL, Instrumental Activities of Daily Living; IQR, interquartile range; MCI, mild cognitive impairment; MMSE, Mini‐Mental State Examination; NPI‐Q, Neuropsychiatric Inventory Questionnaire; SCD, subjective cognitive decline; SD, standard deviation.
Notes: P‐values were obtained using independent samples t tests or analysis of variance for normally distributed continuous variables (mean [SD]), Mann‐Whitney two sample tests for non‐normally distributed continuous variables (median [IQR]), and chi‐square tests for categorical variables (n [%]).
