Associations of PGK1 promoter hypomethylation and PGK1 mRNA level with OS of BRCA patients. a High cg13203541 methylation levels are associated with prolonged OS of BRCA patients. b High PGK1 mRNA levels are associated with short OS of BRCA patients. All statistical tests were two-sided. OS overall survival, BRCA breast carcinoma
