Table 3.

Clinical outcomes stratified by the cut-off value of post-procedural Murray law-based quantitative flow ratio (μQFR) at vessel level.

Variables	μQFR ≤ 0.89 (n = 36)	μQFR > 0.89 (n = 133)	P
Cardiac death	1 (2.78%)	0 (0.00%)	0.21
Target vessel MI	2 (5.56%)	0 (0.00%)	0.04
Target vessel revascularization	10 (27.78%)	9 (6.77%)	0.001
Target lesion revascularization	7 (19.44%)	8 (6.01%)	0.02
VOCE	11 (30.55%)	9 (6.77%)	< 0.001

Patients with more than one event are counted only once for the composite endpoint, although each event is listed separately. P values less than 0.05 are in bold; MI — myocardial infarction; VOCE — vessel-oriented composite endpoint
