AF = atrial fibrillation.
aDenominator 243 (excludes three participants with patch-detected AF for whom AF duration data were not available and three patients with clinically detected AF that was captured after patch discontinuation).
bBinomial test exact p values.
cDenominator 249—all patients who completed the study protocol.
