The result of multivariate statistical analysis in positive mode. PCA score plot of MDA-MB-231 cells and MDA-MB-468 cells were showed in a and b. The green circle represents the control group respectively named 231–0 or 468–0; the blue box represents the middle dose group such as 231–200 or 468–400; the red triangle means the high dose group name 231–400 or 468–600. The EECR treatment groups were obviously distinct with the control groups through the PCA analysis (a, b). The PLS-DA was performed between the high dose group and the control group resulted in R2X = 0.389, R2Y = 0.991, Q2 = 0.959 in MDA-MB-231 cells (c), and R2X = 0.443, R2Y = 0.996, Q2 = 0.972 in MDA-MB-468 cells (d). The permutation plot tests the Statistical validation of the PLS-DA model (n = 200) showing the values of R2 (green circle) and Q2 (blue box) (e, f)
