  • Intermediate (23–32) and high (≥33) SYNTAX scores terciles are pooled together in one group.

  • Cox regression models were stratified by trial.

  • CABG, coronary artery bypass graft surgery; MACCE, major adverse cardiovascular and cerebrovascular events (all-cause death, stroke, MI or all-cause revascularisation); MI, myocardial infarction; PCI, percutaneous coronary intervention.
