Figure 3. Scatter plots of sera relative concentration levels of individual autoantibody among breast cancer patients (NTC = 184, NVC = 197), benign breast disease (NTC = 200, NVC = 109) and normal individual (NTC = 184, NVC = 109) in two cohorts (TC, training cohort; VC, validation cohort).

Figure 5. Positive rates of autoantibodies against eight TAAs or combined five TAAs in individual sera of BC patients, BBD patients and NHC (a, b). The cutoff value was set at the maximum Yoden index when the specificity was greater than 95%. Positive rates of the prediction model with five anti-TAAs autoantibodies among subgroups of BC patients based on tumor stage (c-f), molecular subtypes (g), lymph node metastasis (h), histological type (i) and family history of tumor (j).
