Canadian Registry of AF: Completeness of follow-up of 99% is in the 899 with AF not precipitated by cardiothoracic surgery with a median follow-up of 4.1 years. Three-year visits were completed in 86%. Euro Heart Survey: 80% refers to proportion of patients with known survival status at 1-year. RecordAF: 90% refers to proportion of patients with known cardiovascular death status at 1-year. Belgrade AF Study: 100% refers to proportion of patients with known vitals status during follow-up. AFFECTS: 55% refers to proportion of patients who completed 1-year follow-up. Completeness of follow-up of 100% in the Stockholm Cohort Study of AF, Pappone et al., and Belgrade AF Study was not explicitly stated in the manuscript but implied by the data presentation in the results sections.
