Study design for an emulated trial of a 2 arm, parallel, stratified, adaptive, randomized controlled trial (RCT) of coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) in people requiring myocardial revascularization at high risk (High-Risk REVASC)

Methodological detailsroutinely collected health data, trial emulation methodology, latent class analysis, instrumental variable analysis
- Routinely collected health data
- Trial emulation methodology
