  1. Note: *Significant factors associated with the percentage of extracellular water volume as measured by bioimpedance analysis to total body water volume calculated by the Watson formula identified in the univariate analysis (P < 0.10) were subjected to multivariable analysis. When the eGFR calculated by the revised formula for Japanese patients based on the Modification of Diet in Renal Disease method was used as the dependent variable instead of eGFRCKD-EPI, the results remained similar (data not shown). Additionally, when the serum albumin level was used as the dependent variable instead of UPCR, the independent factors were sex, diabetes mellitus, and serum albumin (data not shown).
  2. Abbreviations: ECW BIA extracellular water as measured by bioimpedance analysis, TBW Watson total body water calculated using the Watson formula, eGFR CKD-EPI estimated glomerular filtration rate using the Chronic Kidney Disease Epidemiology Collaboration equation, UPCR urinary protein-to-creatinine ratio, β standardized regression coefficient, CI confidence interval.
