Figure 3. Overexpression ofRab1B and MMP9 proteins are associated with poor prognosis of CRC patients independent of clinical stage. (A) The overall survival (OS) and progression-free survival (PFS) of CRC patients with high or low Rab1B expression. P value was calculated by Log-rank test. (B) OS and PFS of patients with high or low MMP9 expression. (C) OS and PFS of stage I-II CRC patients with high or low Rab1B expression. (D) OS and PFS of stage III CRC patients with high or low Rab1B expression.
