Model 2 (normal PR, n = 1.057 versus AF, n = 48) identified the following statistically significant characteristics: age (OR 1.104 per year, p = 0.004), EF (OR 0.824, p<0.001), LAD>40 mm (OR 8.651, p<0.001), Troponin>10 pg/ml (OR 3.589, p = 0.015), GFR<60ml/min/1.73m2 (OR 3.786, p = 0.012) and NT-proBNP>125 pg/ml (OR 42.971, p<0.001, Table 3, Model A). The gene discussed is NPPB; the disease is atrial fibrillation.
