Frequency of coronary CT (CCT) findings among each category of yellow plaques
| Grade 1 | Grade 2 | Grade 3 | Non-disrupted | Disrupted | |
| N | 17 | 32 | 16 | 33 | 32 |
| Low attenuated plaque, n (%) | 3 (18)* | 19 (59)* | 11 (69)* | 12 (36)† | 21 (66)† |
| Positive remodelling, n (%) | 4 (24)* | 19 (59)* | 12 (75)* | 11 (33)† | 24 (75)† |
| Ring-like enhancement, n (%) | 1 (0)* | 8 (19)* | 7 (25)* | 2 (6)† | 14 (44)† |
(), % among each category of yellow plaques.
↵* Incidence of each CCT finding was significantly different among plaques of different colour grades (p<0.05 by Kruskal–Wallis test).
↵† Incidence of each CCT finding was significantly different between plaques with and without disruption (p<0.05 by χ2 test).
