Association patterns of urinary sodium, potassium, and their ratio with blood pressure across various levels of salt-diet regions in China
Abstract We aim to evaluate the association of systolic and diastolic blood pressure (SBP and DBP) with estimated urinary sodium (Na) and potassium(K) excretions, and their gram-to-gram Na/K ratio across various salt-diet regions during 2005–2009 in China. A prospective cohort study was conducted to...
