Comparisons of thrombotic angiographic characteristics between lesions in Group 1 and Not-Group 1.
| Characteristics | Group 1 (n = 23) (histologically confirmed thrombus) vs. Not-Group 1 (n = 300)

|||||
|---|---|---|---|---|---|---|
| Group 1 N (%) | Not-Group 1 N (%) | GEE OR (95% CI) | P | Sensitivity % (95% CI) | Specificity % (95% CI) | |
| Complex Ambrose morphology | 1 (4.4) | 18 (6.0) | 1.02 (0.12, 8.74) | 1.0 | 7 (1, 37) | 93 (89, 95) |
| Presence of spherical, ovoid or irregular filling defect | 9 (39.1) | 2 (0.7) | 206 (36.5, 1161) | < 0.0001 | 55 (31, 76) | 99 (97,100) |
| Presence of abrupt vessel cutoff with persistence of contrast | 14 (60.9) | 24 (8.0) | 18.1 (6.64, 49.1) | < 0.0001 | 59 (38, 77) | 92 (88, 95) |
| Presence of intraluminal staining | 8 (34.8) | 4 (1.3) | 44.9 (13.4, 151) | < 0.0001 | 36 (19, 58) | 99 (97, 100) |
| Presence of any coronary filling defect* | 11 (47.8) | 8 (2.7) | 69 (20.4, 234) | < 0.0001 | 60 (37, 79) | 97 (95, 99) |
GEE OR — generalized estimating equations-estimated odds ratio between groups; CI — confidence interval
Group 1 — individual lesions with histologically confirmed thrombus
*
Any coronary filling defect includes spherical, ovoid, irregular, hazy, occlusive filling defects and obstructive coronary dissections
