Performance in the test split of the RF model in the three-class study. Results in more detail are found in Supplementary Table S8. Results from 5-fold cross-validation are given as the balanced accuracy of the model in mean (%) ± standard deviation (%) format.

	Balanced accuracy
Experiment 1: RF	83.84 ± 3.06
Experiment 2: RF + Dimensionality reduction	86.13 ± 3.15
Experiment 3: RF + Feature engineering	86.25 ± 1.77
Experiment 4: RF + Dimensionality Reduction + Oversampling	88.28 ± 1.63
Experiment 5: RF + Feature engineering + oversampling	87.05 ± 2.30
