The liver T1 remained independently associated with elevated NT-proBNP levels in the multivariate logistic regression model, including age, LVEF, and the presence of atrial fibrillation as potential confounders, when measured in the caudate lobe (OR 1.013 [95% CI: 1.004, 1.023]; p = 0.005; Table 4, model 1) and in the right liver lobe (OR 1.012 [95% CI: 1.003, 1.021]; p = 0.009; Table 4, model 2). The gene discussed is NPPB; the disease is atrial fibrillation.
