Restricted cubic spline curve showing the adjusted hazard ratios for all‐cause mortality as a function of baseline serum sodium level. (a) Unadjusted: 140.5 mmol/L was associated with the lowest risk of mortality. (b) Adjusted for age and sex: 140.5 mmol/L was associated with the lowest risk of mortality. (c) Adjusted for age, sex, BMI, hypertension, diabetes mellitus, smoking history, drinking history, ALT, AST, eGFR, abnormal serum potassium level, NT‐proBNP, NYHA functional class IV, LVEF and pharmacotherapy: 140.2 mmol/L was associated with the lowest risk of mortality.
