Figure 2

This schematic depiction of the STICH trial design includes numbers of patients randomized to each stratum. Treatment assignments were MED only for 602 patients, CABG added to MED for 1033 patients, and CABG and SVR added to MED for 501 patients. The 76 Stratum B patients assigned to MED + CABG treatment are used to address both the surgical revascularization hypothesis and the SVR hypothesis. Therefore, 2136 randomized patients provided 2212 patients with potential for primary endpoints for analysis of either or both hypotheses.
