Daily salt intake was estimated from urinary sodium excretion using a validated self\u2010monitoring device and expressed as equivalent sodium chloride (NaCl) (g\/day), and home systolic blood pressure (SBP) was recorded. A cross\u2010sectional analysis compared SBP among the tertiles of salt intake at baseline. Longitudinal analysis was used to compare SBP reduction among the tertiles of salt intake reduction over 3\u2009months. These analyses were adjusted for potential confounders and stratified by obesity, defined as body mass index\u2009\u2265\u200925\u2009kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 1095 participants were included (median age, 57\u2009years; obese, 67.2%).
