Correlations and agreements among AccuFFRivus, AccuFFRct, and FFR. A Correlation between AccuFFRct and FFR. B Agreement between AccuFFRct and FFR. The mean value of AccuFFRct-FFR = 0.00, the upper limit of agreement = 0.16, and the lower limit of agreement = − 0.15. C Correlation between AccuFFRivus and FFR. D Agreement between AccuFFRivus and FFR. Mean value of AccuFFRivus-FFR = − 0.10, the upper limit of agreement = 0.11, and the lower limit of agreement = − 0.13. E Correlation between AccuFFRivus and AccuFFRct. F Agreement between AccuFFRivus and AccuFFRct. The mean value of AccuFFRivus-AccuFFRct = − 0.01, the upper limit of agreement = 0.12, and the lower limit of agreement = − 0.15
