Group analysis of the patients with different icvf values in different tumour area.
| Group | LGG (n = 18) | HGG (n = 24) | Total | P |
|---|---|---|---|---|
| TP icvf = N & PT icvf = N | 13 (87%) | 2 (13%) | 15 | <0.001 |
| TP icvf = N & PT icvf = P | 1 (50%) | 1 (50%) | 2 | |
| TP icvf = P & PT icvf = N | 3 (30%) | 7 (70%) | 10 | |
| TP icvf = P & PT icvf = P | 1 (7%) | 14 (93%) | 15 |
TP: tumour parenchyma; PT: peritumoural area.
The values for TP and PT icvf were determined by regression analysis (TP icvf: N = “<0.306”, P = “≥0.306”; PT icvf: N = “>0.331”, P = “≤0.331”).
