Finally, our analysis shows that TMED9 upregulation is significantly associated with poor survival in LGG patients (p < 0.001, Figure 1I), providing additional support for the comprehensive findings previously reported by Ullah et al. [32] Notably, while TMED9 expression was elevated in GBM, its association with poor survival was close to but did not achieve statistical significance (p = 0.086, Figure 1J). Here, TMED9 is linked to glioblastoma.
