3. Figure 2
Box plot of transforming growth factor (TGF)-β1 in the different groups. Plasma TGF-β1 in the atrial fibrillation (AF) recurrence group was significantly higher than that in the nonrecurrence group among patients with nonparoxysmal AF (34.63±11.98 ng/mL vs 27.33±9.81 ng/mL; P = .026) but not in those with paroxysmal AF (32.21±10.41 ng/mL vs 34.04±12.19 ng/mL; P = .346). There was no difference of TGF-β1 levels between patients with paroxysmal AF and those with nonparoxysmal AF (33.36±11.56 ng/mL vs 32.09±11.70 ng/mL; P = .515).

Atrial fibrillation–free survival by Kaplan-Meier analysis. The sinus rhythm maintenance rate was higher among patients with either transforming growth factor (TGF)-β1≤31.29 ng/mL (A) or left atrial diameter (LAD)≤43 mm (B).

5. Figure 4
Outcome of catheter ablation according to the left atrial (LA) diameter (LAD) and transforming growth factor (TGF)-β1 values. Small LA was defined as LAD≤43 mm, and large LA was defined as LAD>43 mm. Low TGF was defined as TGF-β1≤31.29 ng/mL, and High TGF was defined as TGF-β1>31.29 ng/mL.

Incremental prognostic value of transforming growth factor (TGF)-β1. Bar graph illustrates the improvement in global χ2 value by the addition of TGF-β1 to a Cox regression model including left atrial diameter (LAD).
