Low-Frequency Power Heart Rate Variability by Obstructive Sleep Apnea Group This represents hazard ratios depicted by dots and horizontal lines that reflect the confidence intervals. A 34% increased risk of AF per 1 SD decrease in LF power was observed in those with an OAHI ≥15 (HR: 1.34; 95% CI: 1.08 to 1.66), a finding not observed in those with an OAHI <15 (HR: 1.00; 95% CI: 0.84 to 1.20). The results reflect the statistical model adjusted for the following covariates: age, race, body mass index, waist circumference, self-reported medical history including cardiovascular disease (myocardial infarction or coronary angioplasty or coronary artery bypass graft surgery or stroke), heart failure, hypertension, diabetes mellitus, antiarrhythmic/beta-blocker/calcium channel blocker medications, total cholesterol, alcohol use, chronic obstructive pulmonary disease, and study site. AF = atrial fibrillation; CI = confidence interval; HR = hazard ratio; LF = low frequency; OAHI = obstructive apnea-hypopnea index.
