Multivariable analysis of coronary plaque characteristics for prediction of lesion-specific ischaemia (FFR ≤0.80; N = 484 vessels)

	RR (95% CI) adjusted for age and gender	P-value
NCP ≥185 mm3	1.2 (0.6–2.5)	0.610
LD-NCP ≥30 mm3	4.3 (2.0–9.2)	<0.001
Total plaque volume ≥195 mm3	0.9 (0.4–2.1)	0.834
APV ≥50%	1.0 (0.7–1.5)	0.861
Remodelling index >1.1	1.5 (0.7–3.5)	0.295
Plaque length ≥30 mm	0.8 (0.5–1.3)	0.298

FFR, fractional flow reserve; RR, relative risk; CI, confidence interval; NCP, non-calcified plaque; LD-NCP, low-density non-calcified plaque; APV, aggregate plaque volume.
