The United States preventive services task force recommendation statement on screening for peripheral arterial disease: more harm than benefit?

abstract：:This study explored the association between sodium excretion and blood pressure (BP). A new method was used to minimize the measurement error introduced by the large intrinsic variability of 24-hour sodium excretion. The ratio of intra- to interindividual variation was used to estimate the number of measurements neede...
