Cox proportional hazards regression models were used. Boldface indicates significant findings.
Model 1 adjusts for study site, race, age, BMI, smoking, alcohol use, diabetes, hypertension, coronary heart disease, heart failure, stroke, chronic obstructive lung disease, and chronic kidney disease.
Model 2 adjusts for model 1 covariates and apnea-hypopnea index.
Model 3 adjusts for model 2 covariates and time spent with oxygen saturation as measured by pulse oximetry < 90%.
CV = cardiovascular; HR = hazard ratio; LFCt = lung to finger circulation time.
