Comparable results were observed when the multivariable model adjusted for gender, estimated glomerular filtration rate (eGFR) at admission, atrial fibrillation at admission, NT-proBNP at admission, chronic obstructive pulmonary disease (COPD) and troponin I (TNI) at admission (Supplementary Table A). The gene discussed is NPPB; the disease is atrial fibrillation.
