Flow diagram to show number of participants in REFER study. Flow diagram to show number of participants in REFER study. Step 1 = clinical info +ECG+echo. Step 2 = CDR variables. Step 3 = NT–proBNP result. CDR = clinical decision rule. DNA = did not attend. NT-proBNP = N-Terminal pro-B type natriuretic peptide levels. Clare J Taylor et al.
