Sensitivity analysis examining the impact of different definitions of dementia (unadjusted models)

Dementia definition	N_dementia	Hazard ratio (95% CI)	p value
(1), (2), (3), (4), (5) [primary analysis]	189	0.90 (0.65–1.24)	0.52
(1), (2), (3), (4)	177	0.87 (0.62–1.21)	0.41
(1), (2), (3)	150	0.86 (0.60–1.23)	0.42
(1), (3)	86	0.84 (0.52–1.34)	0.46
(2), (3)	117	1.04 (0.68–1.59)	0.87

Definitions: (1) = Low cognitive test scores and low daily function scores; (2) = MMSE,22; (3) = Self- or proxy-report of dementia or Alzheimer disease diagnosis; (4) = Institutionalization; (5) = Deactivation due to family refusal; CI = confidence interval.
