The results showed that a high expression level of TBX2 was significantly associated with poor RFS and OS of GC patients (p<0.001 and p=0.005, respectively) (Fig. S1), particularly for stage II (p<0.049 and p=0.051, respectively) and stage III (p<0.003 and p=0.033, respectively) patients (Fig. 3). Here, TBX2 is linked to gastric cancer.
