Multiple regression analyses based on the International Classification of Functioning, Disability and Health (ICF) model. Four multiple regression analyses were performed with different dependent variables: SPPB total score, SPPB gait subscore, SPPB static balance subscore, and SPPB transfer subscore. Goodness of the model is displayed with the adjusted coefficient of determination (R2adj) and significance level (p). Independent variables are displayed with standardized regression coefficient (ß) and significance level (p). Significant results (p < .05) are marked bold.
