	CAG-Derived	CTA-Derived	P
CASTLE score	3 (2–3)	3 (2–4)	0.004
Stump anatomy [blunt or invisible]	116 (75.3)	108 (70.1)	0.371
Tortuosity degree [severe or unseen]	41 (26.6)	46 (29.9)	0.613
Length of occlusion [≥ 20 mm]	88 (57.1)	96 (62.3)	0.416
Extent of calcification [severe]	52 (33.8)	74 (48.1)	0.015

Data are presented as median (interquartile range) or number (%)
CAG, coronary angiography; CCTA, coronary computed tomography angiography; CTO, chronic total occlusion
