Figure 2. Forest plot for MACE associated with biodegradable polymer BES versus durable polymer DES.

Figure 2

The squares and the horizontal lines indicate the relative risks, and the 95% confidence intervals for each trial included the size of each square is proportional to the statistical weight of a trial in the meta-analysis. A diamond indicates the effect estimate derived from meta-analysis, with the center indicating the point estimate, and the left and the right ends are the 95% CI. MACE: major adverse cardiac events; BES: biolimus-eluting stents; DES: drug-eluting stents.
