BMI = body mass index; LVEF = left ventricular ejection fraction; PCI = percutaneous coronary intervention; UA = unstable angina; other abbreviations as in Tables 1 and 2.
The multiple regression used an entry criterion of 0.25 and a stay criterion of 0.15.
For the binary variables above, ORs are calculated by comparing “yes” vs. “no” if no specification.
