ITGB1 and glioma: Kaplan-Meier (KM) curve analysis showed that the overall survival time (OS) of patients in the L group (32.90 ± 4.12 months) was significantly longer than OS in the H group (14.60 ± 2.08 months) (p < 0.001) (Figure 5), indicating that expression level of ITGB1 was negatively correlated with the prognosis of glioma.
