Predictors of mortality in ET cases (multivariate Cox proportional hazards models)

Variable	Beta	HR	95% CI	Significance
Cognitive diagnosis
Normal (reference group)
Non-amnestic MCI	−0.41	0.67	0.16–2.83	p = 0.58
Amnestic MCI	0.66	1.93	0.93–3.98	p = 0.08
Dementia	0.98	2.66	1.32–5.34	p = 0.006
Age (years)	0.16	1.18	1.12–1.23	p < 0.001
Number of falls reported in the past year	0.10	1.10	1.01–1.20	p < 0.001

Bolded values are statistically significant (p < 0.05).

CI, confidence interval; HR, hazard ratios; MCI, mild cognitive impairment.
