Medical News: Salt Study Discounts Link to Hypertension - in Cardiovascular, Hypertension from MedPage Today: "Staessen and colleagues found:

Cardiovascular deaths decreased across increasing tertiles of 24-hour urinary sodium excretion. There were 50 deaths in the low group, 24 in the medium tertile, and 10 in the high group – 4.1%, 1.9%, and 0.8% of the cohort, respectively – and the differences were significant at P<0.001.
The risk of cardiovascular death was significantly elevated in the low tertile, with a hazard ratio of 1.56 and a 95% confidence interval from 1.02 to 2.36, which was significant at P=0.04.
24-hour urinary sodium excretion was not associated with incidence of hypertension. There were 187 new cases of hypertension in the low tertile, 190 in the medium, and 175 in the high group over the follow-up period.
In multivariate analyses, a 100-millimole increase in sodium excretion was associated with a systolic blood pressure of 1.71 millimeters of mercury (significant at P<0.001) but no change in diastolic pressure."
