Disease-free survival difference between underwent OFS or non-OFS among CR-score>1.42 premenopausal women with HR + HER2- breast cancer. (A) Disease-free survival difference between underwent OFS or non-OFS among CR-score>1.42 premenopausal women with HR + HER2- breast cancer before PSM. (B) Disease-free survival difference between underwent OFS or non-OFS among CR-score>1.42 premenopausal women with HR + HER2- breast cancer after 1:1 PSM. PSM, propensity score matching; HR + HER2-, hormone receptor-positive human epidermal growth factor receptor 2-negative; OFS, ovarian function suppression; CR-score, composite recurrence risk score
