There was a significant interaction between treatment assignment and SYNTAX score. Patients with intermediate SYNTAX scores (23-32) demonstrated significantly greater angina relief with CABG than with DES-PCI (mean adjusted difference 2.8 points at 1 year), whereas benefits were minimal for patients with low or high SYNTAX scores (-0.1 and 0.3 points, respectively).
Effect sizeIntermediate SYNTAX (23-32): 2.8 points favoring CABG; Low SYNTAX (<=22): -0.1 points; High SYNTAX (>=33): 0.3 points
Follow-up1 year
ComparatorPercutaneous coronary intervention using drug-eluting stents (DES-PCI)
Effect summarymixed; Intermediate SYNTAX (23-32): 2.8 points favoring CABG; Low SYNTAX (<=22): -0.1 points; High SYNTAX (>=33): 0.3 points
