Out of all tested time course model parameters (Fres and Kdec for CD3+, CD4+, CD8a+, CD14+, CD19+, CD56+, and TCRγδ+), only Fres for CD19+ (B cells) was confirmed by the Boruta algorithm as a strong predictor of BC status, and all the others were rejected. The gene discussed is CD14; the disease is breast cancer.
