Table 4.
Mean radiological and pathological tumor size (mm) divided into clinically relevant size intervals by radiological size.
| CT size (mm) | N | Mean CT size (SD) | Mean pathological size (SD) | Mean difference (95% CI) | P value |
|---|---|---|---|---|---|
| ≤40 | 55 | 31.51 (8.17) | 30.58 (10.59) | 0.93 (-1.30 to 3.15) | 0.407 |
| > 40 but ≤70 | 65 | 56.94 (8.50) | 55.14 (16.08) | 1.80 (-1.43 to 5.03) | 0.269 |
| > 70 but ≤100 | 26 | 89.00 (9.26) | 80.96 (29.05) | 8.04 (-2.66 to 18.73) | 0.134 |
| > 100 | 11 | 128.00 (23.04) | 117.73 (27.78) | 10.27 (-2.17 to 22.71) | 0.096 |
