Fig. 6: Normalized viability versus the important features for each random forest model reveals cell composition dynamics in drug response prediction.

The most important features in predicting response to A carboplatin, (B) paclitaxel, (C) PACMA31, (D) N773, and E SC144 versus normalized viability. F Plotting the second most important feature in predicting carboplatin response versus normalized viability reveals the expected relationship between the presence of mesenchymal cells and resistance to carboplatin (higher ratios of MSCs to OVCAR3 are associated with greater resistance to carboplatin).
