Figure 4 Survival of the groups treated with BIMA grafting and single IMA + RA grafting, after propensity-score matching. Values in rows below graph indicate numbers of patients receiving each treatment at corresponding number of years. SIMA, Single internal mammary artery; BIMA, bilateral internal mammary artery.

Survival of the groups treated with BIMA grafting and with single IMA + RA grafting, after propensity-score matching. Long-term survival of patients undergoing composite T-grafting with single, left, IMA and RA is not inferior to that with BIMA grafting. Values in rows below graph indicate numbers of patients receiving each treatment at corresponding number of years.
