Mediation analysis of GNRI and dNLR on the association between eGFRdiff and AF recurrence. (A) When eGFRdiff is in the lower range (< −17.892). GNRI exhibited a significant negative indirect effect on AF recurrence, (B) when eGFRdiff is in the higher range (≥ −17.892). dNLR significantly mediated the positive association between eGFRdiff and AF recurrence.
Abbreviations: AF, atrial fibrillation; GNRI, Geriatric Nutritional Risk Index; dNLR, derived Neutrophil-to-Lymphocyte Ratio.
