† Individual cox proportional hazard regression models were run for each outcome, all models were adjusted for age, gender, OSA, Obesity, hypertension, diabetes, coronary artery disease, COPD, CKD stage 3 or more, prior CABG, hyperthyroidism, alcohol disorder, mitral valve stenosis, prior stroke/TIA, peripheral vascular disease, anemia, heart failure, median household income, primary payer, hospital bed size, and hospital teaching status
‡ Individual cox proportional hazard regression models were run for each outcome, all models were adjusted for CHA2DS2VASC score
