Adjusted Mortality Hazard Ratios for Continuous Sodium Measures

Mortality outcome	Sodium measure	Hazard ratio* (95% confidence interval)	p value
Cardiovascular disease	Sodium per 1,000 mg†	0.88 (0.77, 1.01)	0.07
	Sodium mg per calorie	0.91 (0.72, 1.14)	0.40
	Sodium residuals adjusted per 1,000 mg	0.88 (0.77, 1.01)	0.07
All-cause	Sodium per 1,000 mg	0.94 (0.88, 1.01)	0.11
	Sodium mg per calorie	1.00 (0.88, 1.12)	0.94
	Sodium residuals adjusted per 1,000 mg	0.95 (0.88, 1.02)	0.11

*Hazard ratios (95% confidence intervals) assessed with Cox proportional hazards models adjusting for age, sex, race, education, added table salt, exercise, alcohol use, current smoking, history of diabetes, history of cancer, systolic BP, cholesterol, dietary potassium, weight, treatment for hypertension
