Fig 5

Blue lines represent the HR, and blue transparent areas represent the 95% CI. (A) Association between CONUT score and AF recurrence; (B) Association between NRI and AF recurrence; (C) Association between PNI and AF recurrence. AF, atrial fibrillation; CI, confidence interval; CONUT, controlling nutritional status; HR, hazard ratio; NRI, nutritional risk index; PNI, prognostic nutritional index.
