Figure 3 A 3 x 3 table of 1-year probabilities of event-free survival. Note the decreased survival of discordant percutaneous coronary intervention (PCI)-treated patients, i.e., individuals randomized to PCI whose clinician’s first choice would be toward coronary artery bypass graft (CABG, 61.7) or medical treatment (69.8). White boxes = concordant patients; blue boxes = discordant patients.
