CRP and atrial fibrillation: In the multivariate logistic regression analysis, the result demonstrated that the values of age (OR: 1.030, 95%CI: 1.004–1.057), BMI (OR: 0.863, 95%CI: 0.782–0.952), RDW (OR: 2.917, 95%CI: 1.805–4.715) and LAD (OR: 1.097, 95%CI: 1.004–1.199) were independently risk factors of AF occurrence in HD patients (p < 0.05, respectively) after adjusted gender, number of dialysis, Hgb, serum potassium and CRP in Table 3.
