The EMT/metabolic CTCs subtypes in metastatic and non-metastatic BC patients. a, b Cell number and proportion (in tCTCs) of the EMT subtypes (E-CTCs, H-CTCs, and M-CTCs) in metastatic and non-metastatic groups. c, d Cell number and proportion (in tCTCs) of the metabolic subtypes (GM⁺CTCs and GM⁻CTCs) in metastatic and non-metastatic groups. e Comparison of CTCs subtype proportions between the metastatic and non-metastatic group. **P < 0.01 and NS means not significant (P > 0.05). f The diagnostic performance (AUCs and sensitivity/specificity) of CTCs subtypes in distinguishing cancer metastasis
