Figure 3. — The association between physiological pattern of disease and fractional flow reserve (FFR)/instantaneous wave-free ratio (iFR) discordance. FFR−/iFR+ was significantly more associated with physiologically diffuse pattern of disease, whereas FFR+/iFR− was significantly more associated with physiologically focal pattern of disease. P_Diffuse indicates predominantly physiologically diffuse; and P_Focal, predominantly physiologically focal.
