From: Tolvaptan treatment improves survival of cirrhotic patients with ascites and hyponatremia
Six-month survival of cirrhotic patients with ascites who received tolvaptan or placebo treatment. The Kaplan–Meier survival curves was not statistically significant difference in patients without hyponatremia between tolvaptan and placebo treatment (P > 0.05, a), also in cirrhotic patients with hyponatremia(P > 0.05, b).However, the survival of patients with resolved serum sodium was significantly higher than of those unresolved serum sodium either tolvaptan or placebo treatment(P < 0.01, c)
