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

^#Model adjusted for age, ^{^}model adjusted for age, smoking, beta-blocking agents, mean diastolic blood pressure, 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
