Disease-free survival difference between underwent OFS or non-OFS among premenopausal patients with CR-score ≤ 1.42. (A) Disease-free survival difference between underwent OFS or non-OFS among premenopausal patients with CR-score ≤ 1.42 before PSM. (B) Disease-free survival difference between underwent OFS or non-OFS among premenopausal patients with CR-score ≤ 1.42 after 1:4 PSM. PSM, propensity score matching; OFS, ovarian function suppression; CR-score, composite recurrence risk score
