2. Figure 1
Schematic representation of various patient scenarios with regard to documented and allocated rhythm. Allocated rhythm was determined as the documented rhythm carried backward from each clinic visit, phone call, survey, or procedure (P). Dark bars and light bars indicate time in atrial fibrillation (AF) and time in sinus rhythm (SR), respectively.

3. Figure 2
Single variable predictors of the proportion of time spent in atrial fibrillation (AF). In order of appearance: LA = left atrial diameter (per 5 mm); EF = left ventricular ejection fraction (per 10%); CKD = chronic kidney disease (estimated glomerular filtration rate <30 m:/min); CVA = cerebrovascular accident; OSA = obstructive sleep apnea; DM = diabetes mellitus; HTN = hypertension; CAD = coronary artery disease; Age (per 10 years). CI = confidence interval.

4. Figure 3
Adjusted Kaplan-Meier curve for all-cause mortality by paroxysmal vs persistent atrial fibrillation (AF). Estimates are adjusted using Cox regression and presented for the following covariate values: all-cause death (age 58 years, ejection fraction 56.27%, and no diabetes or coronary artery disease [CAD]).
