The result was present in variables (reference). Beta: standardized regression coefficient; : unstandardized regression coefficient. The variables included in this model were chosen if value ≤ 0.2 in Table 1. Activities of daily living (ADL) score (range 0–6, a higher number indicate higher independence). Instrumental activities of daily living scale (IADLs) score (range 0-8, a higher number indicate higher independence).
