Numbers of subjects enrolled at each time are provided overall and by group to present missing values due to attrition, or incomplete urine collections. Note: Groups did not differ on dietary sodium intake at baseline. Correlations of self-report from the 3-day food record and 24-hr sodium were: .31 at baseline, .41 at 4 M, and .47 at 8 M.
