Impact of SMOTE augmentation on RMBC data. (a) Principal component analysis plots illustrating the distribution of samples before and after SMOTE augmentation. (b) Stacked bar charts showing the relative abundance of the top 20 genera in the original RMBC and SMOTE-augmented RMBC samples. Healthy, healthy control; DFS, disease-free survival; RMBC, recurrence and metastasis of breast cancer; SMOTE, synthetic minority oversampling technique.
