2. Fig. 1
The hazard of recurrence of tense ascites requiring therapeutic paracentesis despite ongoing active medical treatment with sodium restriction and stepped-care diuretic use for patients managed with medical therapy and TP versus medical therapy; TP and TIPS is shown in the form of a Kaplan–Meier curve. TIPS was associated with significantly better control of ascites (P < ; Wilcoxon test) with a lower rate of recurrence of tense ascites compared with TP. The number of subjects at risk in each arm is shown below the figure.
