Note: Statistical analysis used nonparametric tests and Fisher’s exact tests. P1, P3, P5 means the significance compared with GC group, respectively. P2, P4, P6 means the significance compared with MA or SRCC group, respectively. P7 means the significance compared with HMDA group; P8 means the significance compared with PDA group; P9 means the significance compared with MA or SRCC group.
