The present study included 492 patients who underwent hemodialysis from June 1st 2016 to May 31st 2020. Corrected salt intake by ideal body weight was the main predictor of outcomes. Ideal body weight was calculated assuming that the ideal body mass index is 22 kg/m2 for the Japanese population. We grouped patients by the interquartile range of corrected salt intake: Q1 (< 0.13 g/kg/day), Q2 (0.13- < 0.16 g/kg/day), Q3 (0.16- < 0.20 g/kg/day), and Q4 (> 0.20 g/kg/day). The multivariate Cox proportional hazards model was used to determine the association between corrected salt intake and mortality, adjusting for potential confounders. The outcomes considered were all-cause mortality and cumulative incidence of cardiovascular events at year 4.
