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 4 All-cause mortality rates (n/1000), and unadjusted HR for tertiles of urinary sodium excretion with their 95% confidence interval

	Tertile 1 (< 173 mmol/day) (n = 61)	Tertile 2 (173–229 mmol/day) (n = 59)	Tertile 3 (230–491 mmol/day) (n = 60)
