Kaplan-Meier survival curves stratified by dysnatremia categories. (A) Survival curve of hyponatremia, normonatremia, hypernatremia and mixed dysnatremia; (B) Survival curve of community-acquired vs. hospital-acquired dysnatremia; (C) Survival curve of improved vs. persistent dysnatremia, “hypo to hyper” vs. “hyper to hypo” mixed dysnatremia. The vertical lines represent censored subjects. The follow-up duration is different for each subject because it is censored at the end of hospitalization. CA – community-acquired; HA – hospital-acquired.
