NPPB and atrial fibrillation: After adjusting for the common risk factor (age, NT-proBNP, serum creatinine, FT3, and FT4), stepwise multiple logistic regression analysis revealed that TSH levels were significantly related to AF incidence.Compared to patients with TSH (0.55 ~ 2.49 mIU/L) group, the adjusted odds ratio of AF for TSH(<0.55) group, TSH (2.50~9.99) group, TSH (≥10.00 mIU/L) group were 1.481 (95% CI 0.485~4.518,P=0.490), 1.977 (95%CI 1.115~3.506, p=0.02), 4.301 (95%CI 1.059~17.476, P=0.041), respectively (Figure 1).
