The overall survival difference was highly significant (p < 0.0001 for both pre- and post-operative subgroups).
Univariable survival analysis indicated that H3K27M mutation was associated with poorer prognosis, although the difference did not reach statistical significance (HR = 0.71, 95% CI: 0.43–1.17, p = 0.184).
