Figure 5: Bland-Altman Plots Demonstrating Agreement Between vFFR and Measured FFR

The solid line indicates bias (mean delta), and the interrupted lines represent the upper and lower limits of agreement (SD: ±1.96). (A) Agreement for vFFRps-trns, and (B) agreement for vFFRsteady. Note the high number of cases in the clinically important FFR range from 0.7 to 0.9.
