In this paper, the following corrections should be made:
1. On page 73, the first sentence of the “Visual CMR analysis versus FFR” paragraph gives incorrect numbers for visual perfusion analysis. The correct numbers are: perfusion was abnormal for 27 (not 30 as written) and normal for 99 (not 96 as written) territories. All data analyses presented in the paper used the correct numbers and were thus unaffected by this error.
2. On page 73, the title of Figure 2 should read ”ROC showing the sensitivity and specificity of FFR to detect defects identified by visual CMR analysis.”
3. On page 74, left column, line 7, the significance of the difference between the correlations for MPR and FFR with diameter stenosis reported as p < 0.0001 strictly applies only to the difference between the r values of 0.59 and −0.47, not the closeness of the correlation. The closeness of correlation would have a 2-sided p value of 0.026.
The authors apologize for these errors.
