Kaplan-Meier Plots of Survival stratified by Activin expression status (A) combined UICC and Activin expression status (B) CD4⁺ cell infiltration status (C) and for combined Activin and CD4⁺ cell infiltration status (B). High Activin expression and high CD4 infiltration are positive prognostic for survival in GC patients. The survival benefit of activin is exclusively seen in UICC III stage (B) and in combination with CD4⁺ cell high infiltration status (D). Significance calculated by log-rank test
