Scatter plots show a moderate correlation between invasive FFR and FFRCT-1 cm (A) and between invasive FFR and FFRCT-lowest (B), a good correlation between invasive FFR and FFRCT-2 cm (C) and between invasive FFR and FFRCT-3 cm (D). Bland–Altman plots show a very mild difference between invasive FFR and FFRCT-1 cm (E), invasive FFR and FFRCT-2 cm (F), invasive FFR and FFRCT-3 cm (G), invasive FFR and FFRCT-lowest (H) on a per-vessel bias. FFR, fractional flow reserve; FFRCT, CT fractional flow reserve; FFRCT-1 cm, FFRCT measured at 1 cm distal to the lower border of the target lesion; FFRCT-2 cm, FFRCT measured at 2 cm distal to the lower border of the target lesion; FFRCT-3 cm, FFRCT measured at 3 cm distal to the lower border of the target lesion; FFRCT-lowest, lowest FFRCT value in the distal vessel tip
