Fig. 4From: A high CD8 to FOXP3 ratio in the tumor stroma and expression of PTEN in tumor cells are associated with improved survival in non-metastatic triple-negative breast carcinomaOverall Survival of triple-negative breast cancer patients in the METABRIC cohort according to the ratio between the expression of CD8A and FOXP3. The groups were stratified using optimal cut-off derived by the max-stat method. Patients with the ratio between CD8A and FOXP3 expression higher than or equal to 1.34 had better overall survival. Survival curves were calculated using the Kaplan-Meier method and compared by the log-rank testBack to article page
