Figure 1. Prevalence of atrial fibrillation is shown in the general population, and in patients with different stages of chronic kidney disease (CKD) including end-stage renal disease (ESRD). In some studies, different stages are pooled together which is indicated by wider srectangles above the CKD stages. CKD stage 1: eGFR ≥ 90 ml/min/1.73m²; CKD stage 2: eGFR 60-89 ml/min/1.73m²; CKD stage 3: eGFR 30-59 ml/min/1.73m²; CKD stage 4: eGFR 15-29 ml/min/1.73m²; CKD stage 5: eGFR <15 ml/min/1.73m².
