Figure 4. Overall survival analysis of the 20 hub genes in GC. Overall survival of patients with GC with low and high levels of CDK1 (A), CCNA2 (B), AURKB (C), BUB1B (D), TOP2A (E), BIRC5 (F), CCNB2 (G), BUB1 (H), CENPF (I), KIF2C (J), PBK (K), NCAPG (L), TPX2 (M), KIF15 (N), SST (O), CHGA (P), GNG7 (Q), NPY (R), GHRL (S), and CCKBR (T) are displayed using Kaplan–Meier curves. Log-rank P < 0.05 was regarded as statistically significant. GC, gastric cancer; HR, hazard ratio.
