| VEGF expression | N | R2* value Mean ± Std (Hz) | t value (P) |
|---|---|---|---|
| Negative | 8 | 56.1 ± 18.0 | t = 1.502 (P = 0.146)* |
| Weakly positive | 18 | 45.4 ± 18.9 | t = −1.882 (P = 0.065)† |
| Moderately positive | 34 | 56.4 ± 16.5 | t = −0.060 (P = 0.952)‡ |
| Strong positive | 38 | 54.8 ± 19.8 | t = 0.162 (P = 0.872)§ |
| F (P) | 1.895 (0.136) |
R2* value, LSD-t test: *Negative group and weakly positive group; †Weakly group and strong group; ‡Negative group and moderately positive group; §Negative group and strong positive group; Weakly positive group and moderately positive group: t = –2.407, P = 0.020; moderately group and strong group: t = 0.377, P = 0.707.
