Authors' conclusion

In patients with CCS, noncardiac mortality in late follow-up was similar for revascularization plus MT compared with MT alone.

Pooled result

As reported in the abstract

No significant difference in noncardiac mortality between the assigned treatment groups (RR, 95% CI)

RR: 1.09; 95% CI: 0.94-1.26; P = 0.26

Cumulative Z-curve within the nonsignificance area, reaching futility boundaries
