Urinary sodium concentration predicts time to major adverse coronary events and all-cause mortality in men with heart failure over a 28–33-year period: a prospective cohort study

Table 5 Cox survival analysis: Hazard ratio (HR) and 95% confidence interval of all-cause mortality rate across tertiles of urinary sodium excretion

Urinary sodium excretion	HR	95%CI	Chi^2*	p value

Tertile 1	1.00	Reference
Tertile 2	0.61	0.41, 0.91
Tertile 3	0.90	0.62, 1.33
Model 2^#			6.57	0.04
Tertile 1	1.00	Reference
Tertile 2	0.62	0.42, 0.92

^#Model adjusted for age, ^{^}model adjusted for beta blocking agents, income, age, smoking, BMI, and diabetes, tertile 1 < 173 mmol/day, tertile 2 = 173–229 mmol/day, tertile 3 = 230–491 mmol/day, * d.f. = 2, Chi² results are from testing of Cox regression beta coefficients
