Forest plots with log-rank p-values and hazard ratio (HR) of OS in the GSE96058 cohort, and OS and DSS in the METABRIC cohort between low and high ROS score in the whole, ER+/HER2−, HER2+ and TNBC subgroups. Log-rank test was used to calculate p values. DSS, disease-specific survival; ER, estrogen receptor; HER2, human epidermal growth factor 2; OS, overall survival; TNBC, triple-negative breast cancer
