Abbreviations: APOR, adjusted prevalence odds ratio; BMI, body mass index; CAD, coronary artery disease; CHF, congestive heart failure; CI, confidence interval; CVA, cerebrovascular accident; DM, diabetes mellitus; ESRD, end-stage renal disease; GN, glomerulonephritis; Hb, hemoglobin; HTN, hypertension; PVD, peripheral arterial disease.

^aAs patients were classified as having HTN, for analytic purposes, whether HTN was a cause of ESRD or was listed as a comorbidity on the CMS 2728 form, the APOR represents the association of HTN with chronic atrial fibrillation only in individuals who did not have HTN as the cause of ESRD. The APOR for DM is conceptually identical.

^bAmong individuals with both HTN and DM as comorbidities.

^cAmong individuals with HTN.

^dAmong individuals with DM.

^eAmong individuals irrespective of HTN or DM status.
