Clinical significance of CHIP and TRAF2 expression in GC patients. a Representative images of CHIP and TRAF2 expression in GC and adjacent non-neoplastic tissues were detected by IHC. Tumor represents GC tissues; Adjacent represents the non-neoplastic tissues; magnification 100× and 200×). b The stacked bars indicate the percentages of GC samples with high or low CHIP expression levels relative to the total number of tissues. c The stacked bars indicate the percentages of GC samples with high or low TRAF2 expression levels relative to the total number of tissues. d Kaplan–Meier curves that depict the 5-year OS according to the CHIP expression in patients with GC. CHIP-low represented the CHIP low expression group; CHIP-high represented the CHIP high expression group. The difference of OS between the two groups was determined using a log-rank test. e Kaplan–Meier curves that depict the 5-year OS according to the TRAF2 expression in patients with GC. TRAF2-low represented the TRAF2 low expression group; TRAF2-high represented the TRAF2 high expression group
