(G) Kaplan-Meier plot analysis of the metastasis-specific survival of 85 TNBC patients with low or high expression of MIG-6. MIG-6 protein expression in the 85 TNBC specimens was determined by H-score and widely distributed. MIG-6 expression greater than or equal to the median is classified as "high," while expression less than the median is classified as "low."
