Method agreement CFVR vs MFRLAD. “Bland-Altman plot”: Differences vs averages of myocardial flow reserve (MFR) measured by PET of the LAD-territory (MFRLAD) versus coronary flow velocity reserve (CFVR) measured by transthoracic Doppler echocardiography of the LAD. a include all participants and (b) display measurements of participants with no prior myocardial infarction (No-MI) of the LAD territory. Examinations performed in a week are marked by closed squares and triangles for participants without and with prior myocardial infarction of the LAD territory, respectively. Examinations performed more than a week apart are marked by open squares and triangles for participants without and with prior myocardial infarction of the LAD territory, respectively. Limits of agreement for exams performed within a week (red dashed lines) and combined for all exams (green dotted lines) are displayed together with corresponding mean differences (bias) for a week (red full line) and all differences (green dashed and dotted line)
