Figure 5: Progression-free survival (PFS) and overall survival (OS) in the gross total resection (GTR) group and the non-GTR group. (a) PFS seems to be better in the GRT group than that in the non-GTR group, although the difference is not significant (P = 0.079). (b) OS is better in the GTR group than in the non-GTR group (P = 0.043) |
