| Variables | Highly-differentiated (n=23) | Moderately-differentiated (n=63) | Poorly-differentiated (n=42) | F | P |
|---|---|---|---|---|---|
| RT | 11.09±1.87b | 9.86±2.38a | 6.39±1.09ab | 56.753 | <0.001* |
| TTP | 12.18±3.03b | 9.19±2.75a | 7.56±2.35ab | 22.108 | <0.001* |
| Enhancement rate | 0.63±0.16 | 0.76±0.15 | 0.80±0.14ab | 15.000 | <0.001* |
| mTT | 89.33±21.76 | 95.08±34.01 | 97.47±25.26 | 0.573 | 0.565 |
