Diagnostic performance of Collaboration for the Diagnosis and Evaluation of Heart Failure (CoDE-HF) score across patient subgroups: negative predictive value of CoDE-HF rule-out score of 4.7 in patients without previous heart failure across patient subgroups. CoDE-HF incorporates N-terminal pro-B-type natriuretic peptide concentrations as continuous measure and predefined simple objective clinical variables (age, estimated glomerular filtration rate (eGFR), haemoglobin, body mass index, heart rate, blood pressure, peripheral oedema, chronic obstructive pulmonary disease (COPD), and ischaemic heart disease) to provide individualised assessment of likelihood of diagnosis of acute heart failure
