Estimation of total extent for all modalities and compared to histopathology
| Method | Total extent (mm) | Difference from histopathology1 (mm) | LOA2 (mm) | |
|---|---|---|---|---|
| CEM | Mean (SD) | 33.8 (28.3) | − 1.4 (18.5) | − 37.523; 34.812 |
| Median (Q1; Q3) | 22 (14; 50) | 0 (− 12; 5) | ||

| Ultrasound | Mean (SD) | 26.8 (24.2) | − 8.4 (24.3) | − 55.977; 39.266 |

Difference is calculated as follows: Total extent from estimation method − total extent from histopathology
