Footnote: Conditional negative binomial regression model with random effects for GP; Number of caregivers’ rejection was the predictor of interest; p-values are given one-sided, CI = Confidence interval, MMST = Mini Mental State Test ranging from 0 to 30 (higher score indicates better cognitive functioning), B-ADL = Bayer Activities of Daily Living Scale ranging from 0 to 10 (lower score indicates better performance), GDS = Geriatric Depression Scale ranging 0–15 (score ≥ 6 indicates depression), SF-12 = 12-Item short form survey assessing physical and mental health, BSI-18 = brief symptom inventory short form assessing syndromes of somatization, depression, and anxiety
