Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Dietary sodium intake is closely associated with the prognosis of chronic kidney disease (CKD) patients. Previous studies have developed an equation for estimating dietary sodium intake through 24-hour urine sodium in CKD, which are not applicable in peritoneal dialysis patients. This study aims to develop a novel equation for estimating dietary sodium intake in 20 anuric peritoneal dialysis patients, using accurately measured dietary sodium as the dependent variable and peritoneal sodium clearance and its related variables as independent variables, and then to validate the precision and accuracy of the novel equation in another 20 anuric peritoneal dialysis patients.
