  Figure 2. The impact of the SII on the AF recurrence after RFCA (A) and comparison of the SII level between the recurrent group and non‐recurrent groups (B) in the overall study population. AF, atrial fibrillation; RFCA, radiofrequency catheter ablation; SII, systemic immune‐inflammation index.

  Figure 3. Nonlinear associations between SII concentration and the prevalence of AF recurrence. When the SII concentration was greater than 444.77 × 109/L, the prevalence of AF recurrence increased with SII concentration. When the SII concentration was less than 444.77 × 109/L, the prevalence of AF recurrence reached a plateau. AF, atrial fibrillation; RCS, restricted cubic spline; RFCA, radiofrequency catheter ablation; SII, systemic immune‐inflammation index.
