Mortality by admission serum sodium category, stratified by decile of age. The proportion of patients who experienced in-hospital death was highest among those with hypernatremia. Patients with hyponatremia also had a higher proportion of death as compared with normonatremia across age deciles, with the exception of patients ≥80 years old, where hyponatremia and normonatremia had similar proportions of in-hospital death.
