Kaplan-Meier curves of EFS between actual pCR and non-pCR in a training cohort b external test cohort, and c entire cohort. Kaplan-Meier curves of EFS between high and low BCRP scores based on cutoff valve of 0.59 in d training cohort e external test cohort, and f entire cohort. EFS event-free survival, pCR pathological complete response.
