The correlation of the expression of the 11 autophagy‐related lncRNAs with clinicopathological factors. A, ER expression. B, PR expression. C, HER2 expression. D, Subtypes (luminal A/B; HER2 amplification; TNBC: triple‐negative breast cancer). E, TNM stage. F, Tumour size (T1: <2cm; T2: ≥2cm and < 5cm; T3: ≥5cm; T4: invasion of chest wall and/or skin). G, N classification (N0: no lymph node metastasis; N1: 1‐3 lymph node metastasis; N2: 4‐9 lymph node metastasis; N3: ≥10 lymph node metastasis). H, M classification (M0: no distant metastasis; M1: distant metastasis). ns: no statistical significance, *P < .05, **P < .01, ***P < .001, ****P < .0001
