Kaplan-Meier estimates of survival by natremia group. Population at risk during the follow-up is tabulated below the graph. The 6-months, 1-year, 3-year and 5-year cumulative survival rates were 98.1% ± 0.4%, 97.8% ± 0.5%, 96.3% ± 0.7%, 95.5% ± 4.5% respectively in normonatremic patients versus 91.4% ± 2.3%, 89.2% ± 2.6%, 85.8% ± 3.0%, 83.8% ± 16.2% respectively in the hyponatremic group.
