To further validate the potential prognostic significance of our findings, we researched publicly available platforms of expression analysis, including SurvExpress,19 K‐M Plotter20 and PrognoScan.17 First, we estimated the prognostic significance of ARID1A in predicting the RFS rates, which frequently reflect chemotherapeutic responses in breast cancer patients. The gene discussed is ARID1A; the disease is breast carcinoma.
