Survival associations of chitinase-like family genes and CHID1 in GBM. Kaplan-Meier survival analyses showing the association between expression levels of CHI3L1, CHI3L2, CHID1, and CHIT1 and overall survival in patients with GBM (A-D). Patients were stratified into high- and low-expression groups, and survival differences were evaluated using the log-rank test. Among these genes, CHID1 expression showed a significant association with patient survival. (E-H) Box plots showing the relationship between CHID1 expression and clinicopathological characteristics in GBM, including tumor grade, gender, age status, and progression status. Gene expression levels are displayed with individual sample points, and statistical comparisons were performed using appropriate parametric tests.
