Sample composition for different molecular characteristics and mismatch signaturesa
| Groupings | Group 1 | Group 2 |
|---|---|---|
| (A) IDH-mutation status | Mutated (n = 83) | Wild-type (n = 22) |
| (B) 1p/19q codeletion status | Noncodeleted (n = 56) | Codeleted (n = 27) |
| (C) IDH mutant and 1p/19q noncodeleted versus others | Noncodeleted (n = 56) | Others (n = 49) |
| T2-FLAIR mismatch type | ||
| (D) In all LGGs | Mismatch (n = 11) | No mismatch (n = 94) |
| (E) In IDH-mutant LGGs | Mismatch (n = 11) | No mismatch (n = 72) |
| (F) In IDH -mutant and 1p/19q noncodeleted LGGs | Mismatch (n = 11) | No mismatch (n = 45) |
↵a Three subjects were excluded due to missing data. The 6 groupings based on the molecular status and mismatch indicators are indicated as (A)–(F).
