Subgroup analysis of discrimination of the nomogram. a Comparison of the nomogram in the Luminal B-like and the Luminal A-like cohort. Luminal B-like: The AUC is 0.772 (95% CI 0.739–0.810); Luminal A-like: The AUC is 0.698 (95% CI 0.632–0.764); Delong’s test P = 0.048. b Comparison of the nomogram in the large tumor cohort and the small tumor cohort. Large tumor: The AUC is 0.847 (95% CI 0.804–0.890); Small tumor: The AUC is 0.779 (95% CI 0.746–0.813); Delong’s test P = 0.016
