| LGGs (WHO grade II/III gliomas) | |
| Nonlobar location | 2.38 |
| Proportion of enhancing tumor of >33% | 1.66 |
| Multifocal/multicentric distribution | 2.93 |
| Poor definition of nonenhancing margin | 1.30 |
| WHO grade II gliomas | |
| Side of tumor epicenter (central) | 1.36 |
| Multifocal/multicentric distribution | 7.00 |
| Pial invasion | 1.48 |
| Ependymal involvement | 1.62 |
| WHO grade III gliomas | |
| Nonlobar location | 2.33 |
| Proportion of enhancing tumor of >33% | 1.25 |
| Multifocal/multicentric distribution | 2.27 |
| Cortical involvement | 0.99 |
