Figure 1. hsa-miR-4443 decreased in patients with atrial fibrillation (AF). A, Serum hsa-miR-4443 expression level was determined by qRT-PCR. B, ROC analysis was performed to evaluate the diagnostic efficacy of serum hsa-miR-4443 for persistent AF. Horizontal lines indicate median and interquartile range. ***P<0.001 vs control (Mann-Whitney U test, two-sided).
