Figure 8 displays a forest plot for the random-effects model for studies evaluating revascularization (primarily CABG) versus medical therapy in stable angina with long-term followup. The summary odds ratio in women was 0.56 (CI, 0.32 to 0.96) and in men was 0.62 (CI, 0.31 to 1.24). The test for heterogeneity was not significant for women (p=0.15) but was significant for men (p=0.0004). These results show that CABG was significantly better in reducing cardiovascular events than optimal medical therapy was in women (effect size p=0.04) but not in men.
