	All gliomas % (range)	FRAT1-positive %	FRAT1-negative %
Pi	33.06 ± 20.93 (0.8 to 85.3)	45.59 ± 16.78%	14.03 ± 8.51%
Ii	26.70 ± 19.3 (0 to 69.0)	36.72 ± 18.29%	11.49 ± 10.51%
MVD	66.59 ± 31.05 (14 to 145)	75.10 ± 31.58	53.68 ± 25.75

Pi, proliferative index; Ii, invasive index; MVD, microvessel density.
