Adiponectin and NT-proBNP levels between patients with and without AF recurrence (A) and receiver-operating characteristic (ROC) curves of the adiponectin and NT-proBNP levels for differentiating AF recurrence (B). Magnitude of the bar graph and error bar indicate the mean±SD of the adiponectin levels and the median and interquartile ranges of the NT-proBNP levels. Values between the 2 groups were compared using a two-tailed t test or Mann–Whitney U test. AF, atrial fibrillation; NT-proBNP, N-terminal pro-brain natriuretic peptide.
