IRS, Pi, Ii, and MVD in FRAT1-positive and FRAT1-negative groups of gliomas.
| All gliomas % (range) | FRAT1-positive % | FRAT1-negative % | t | P | |
|---|---|---|---|---|---|
| Pi | 33.06 ± 20.93 (0.8 to 85.3) | 45.59 ± 16.78% | 14.03 ± 8.51% | t = 10.21 | P < 0.001 |
| Ii | 26.70 ± 19.3 (0 to 69.0) | 36.72 ± 18.29% | 11.49 ± 10.51% | t = 7.21 | P < 0.001 |
| MVD | 66.59 ± 31.05 (14 to 145) | 75.10 ± 31.58 | 53.68 ± 25.75 | t = 2.94 | P = 0.0045 |
Pi, proliferative index; Ii, invasive index; MVD, microvessel density.
