Figure 6. Combined expression of Rab1B and MMP9 proteins predicts the outcome of adjuvant chemotherapy in CRC patients. CRC Patients were stratified into three risk groups by the combined risk score of Rab1B and MMP9 protein expression. Kaplan-Meier survival was used to compare OS and PFS of CRC patients with or without adjuvant chemotherapy in low risk group (A), intermediate risk group (B), and high risk group (C).
