3. Figure 2
Forty-two-day mortality (top) and AEs (bottom) irrespective of the vasoactive control treatment in full reports, according to whether adequate generation of the randomization list and adequate treatment allocation concealment were used or not. RCTs are identified by the first author and the year of publication. RD, risk difference; EVS, endoscopic variceal sclerotherapy.

4. Figure 3
Egger’s publication bias plot. The standardized risk difference (EVS minus pharmacologic interventions) for 42-day mortality is plotted against the precision of the risk difference along with the regression line and the CI (arrows) about the intercept. Failure of this CI to include 0 would indicate asymmetry in the funnel plot and might give evidence of publication bias. Standardized risk difference = risk difference/standard error. Precision of risk difference = 1/standard error.
