Multivariate linear regression analysis of TMR and tumor biological indices.

Variable	Standardized coefficient	t	P
HIF-1a (%)	0.554	3.575	0.002
Glut-1 (%)	-0.059	- 0.302	0.766
Ki67 (%)	0.267	1.380	0.185
P53 (%)	0.053	0.528	0.604
MVD	0.218	2.004	0.060

The percentage of HIF-1α positive cells in tumor tissue was indicated as an independent factor for TMR value (p < 0.01).
