| H&E | Immunohistochemistry | ||
| Positive n (%) | Negative n (%) | Total n (%) | |
| LVI | |||
| Positive | 14 (11.4) | 3 (2.4) | 17 (13.8) |
| Negative | 21 (17.1) | 85 (69.1) | 106 (86.2) |
| Total | 35 (28.5) | 88 (71.5) | 123 (100) |
| BVI | |||
| Positive | 3 (2.4) | 2 (1.7) | 5 (4.1) |
| Negative | 16 (13.0) | 102 (82.9) | 118 (95.9) |
| Total | 19 (15.4) | 104 (84.6) | 123 (100) |
LVI = lymphatic vessel invasion; BVI = blood vessel invasion; H&E = hematoxylin and eosin; n = number of cases
Kappa value for LVI= 0.433 (95% confidence interval: 0.229 to 0.636)
Kappa value for BVI= 0.198 (95% confidence interval: -0.144 to 0.541)
