Adjusted analysis by multiple logistic regression of risk of decline in ADLs until follow-up (3 months)

	OR (95% CI)	P-value
Clinic
CGA unit (intervention group)	0.093 (0.052–0.164)	<0.0001
Conventional care (control group)	REF
Sex
Female	1.358 (0.775–2.382)	0.285
Male	REF
Age	1.031 (0.981–1.084)	0.231
Charlson Comorbidity Index score	0.955 (0.803–1.136)	0.601

Notes: Decline in ADLs refers to a minimum one-step increase of dependence according to the ADL Staircase. OR indicates odds ratio. Patients were excluded from the analysis if information of ADL score was missing at index and/or follow-up. Age, sex, and Charlson Comorbidity Index score were potential confounders and used as covariates. They were tested for collinearity with the use of the variance inflation factor. All variables had a variance inflation factor value <2.5, which does not indicate collinearity.
