Histological features versus molecular classification in the training cohort.
| Group 1 | Group 2 | p | |
|---|---|---|---|
| Astrocytic component | 23/27 (85%) | 8/19 (42%) | <0.005 |
| Dysplastic neurons | 22/27 (81%) | 4/19 (21%) | <0.005 |
| Inflammation | 15/27 (55%) | 2/19 (11%) | <0.005 |
| EGB | 13/27 (48%) | 1/19 (5%) | <0.005 |
| Oligodendrocyte‐like cells | 9/27 (33%) | 17/19 (89%) | <0.005 |
| Glioneuronal element | 1/27 (4%) | 10/19 (53%) | <0.005 |
| Floating neurons | 2/27 (7%) | 6/19 (32%) | 0.051 |
| Microvascular proliferation | 2/27 (7%) | 3/19 (16%) | 0.635 |
| Calcification | 14/27 (52%) | 7/19 (37%) | 0.377 |
| Anaplasia | 3/27 (11%) | 1/19 (5%) | 0.632 |
| Rosenthal fibres | 4/27 (15%) | 2/19 (11%) | 1 |
Note: A prominent astrocytic component, dysplastic neurons, inflammation, and eosinophilic granular bodies (EGB) associate with Group 1. Oligodendrocyte‐like cells, a specific glioneuronal element, and floating neurons associate with Group 2.
