Variable	Intervention group (n = 201)		Control group (n = 140)		p-value
Shared-housing arrangements (SHA):
Number of SHA staff M (SD)	11.00	(6.8)	11.50	(7.7)	0.27
Number of residents per SHA M (SD)	9.54	(2.6)	9.49	(1.9)	0.84
Participants:
Age, M (SD)	85.40	(8.19)	83.8	(8.7)	0.08
Sex
Female, n (%)	162	(80.6)	98	(70.0)	0.03
Care level, Mdn (IQR)	3.00	(1.0)	3.00	(1.0)	0.40
MMSE sum score, M (SD)	19.20	(6.02)	17.90	(6.81)	0.25

Note. M Mean, SD Standard deviation, Mdn Median, IQR Interquartile range, Care level = higher scores indicate a higher need for care, Range: 0-5; MMSE Mini-Mental State Examination, lower scores indicate more severe cognitive impairment, and a score between 0 and 9 indicates severe dementia, Range: 0-30; Charlson Index = Updated and validated Charlson Comorbidity Index by Quan et al., higher scores indicate a higher 1-year comorbidity-related mortality rate, Range: 0-24, whereby a score of 5 is associated with an 85% 1-year mortality risk; Barthel Index, Range: 0-100, higher scores indicate better performance of activities of daily living
