Survival analysis of breast cancer patients, with the KM Plotter tool, indicates no statistically significant difference in terms of overall survival or relapse‐free survival (RFS) when patients were stratified in the upper and lower quartiles for their gene expression levels of ERO1A (Figure 6a) and EIF2AK3 (PERK) (Figure 6b). The gene discussed is EIF2AK3; the disease is breast carcinoma.
