CYGB and atrial fibrillation: Based on the univariate logistic analysis, the variables of male, DM, HGB, age, AST, sCr and PAGln (p < 0.1) were selected for multivariate logistic analysis indicating that PAGln plasma levels (odds ratio (OR): 1.437, 95% confidence interval (CI): 1.143–1.806, p = 0.002) and age were independent risk factors for AF (OR: 1.103, 95% CI: 1.026–1.186, p = 0.008) (Table 2).
