Data are shown as the number (%) of patients, mean ± SD values, or median (25th, 75th percentile) values. % = % of the total of 45 and 47 patients who underwent a DES implantation in the edoxaban monotherapy group and combination therapy group, respectively. AF, atrial fibrillation; BMI, body mass index; CABG, coronary artery bypass grafting; DES, drug eluting stent; Hb, hemoglobin; NT-pro BNP, N-terminal probrain natriuretic peptide; PCI, percutaneous coronary intervention; POBA, plain old balloon angioplasty. Determined by the t-test, chi-square test, or fisher’s exact test.
