BRAF and neoplasm: We found that among all KIAA1549::BRAF fusion-positive LGGs, P/LP carriers had significantly worse event-free survival (EFS) versus non-carriers in univariate (p=0.031, Figure 6B) and multivariate cox proportional hazards models accounting for extent of tumor resection, predicted sex, and age at diagnosis (HR=2.67, p=0.03; Figure 6C).
