Correlations and agreements among target-QFR, vessel-QFR, and FFR. A Correlation between target-QFR and FFR. B Agreement between vessel-QFR and FFR. The mean value of target-QFR—FFR = 0.0016, the upper limit of agreement = 0.104, and the lower limit of agreement =—0.072. C Correlation between vessel-QFR and FFR. D Agreement between vessel-QFR and FFR. Mean value of vessel-QFR—FFR = 0.010, the upper limit of agreement = 0.108, and the lower limit of agreement = 0.087
