Figure 12 Trial Sequential Analysis using fixed-effect meta-analysis in the reperfusion era. The required information of 49,990 patients is based on an anticipated intervention effect of 10% relative risk reduction, a control event proportion of 7.36% (estimated from the cumulated comparator event proportion), absence of heterogeneity (diversity = 0%), and α = 0.05 and β = 0.10.
