Expression levels of TGF-β1 in two AF groups. Correlation between hsa_circ_0004104 and TGF-β1. a PsAF patients had significantly higher level of TGF-β1 than PAF, p < 0.001. b Negative correlation between hsa_circ_0004104 and TGF-β1 verified by linear regression (r = −0.797, p < 0.001). Larger bubble size referred to higher level of plasma TGF-β1. ***p < 0.001
