Performance in the test split of the RF model in the four-class study. Results in more detail are found in Supplementary Table S9. 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	67.21 ± 4.50
Experiment 2: RF + Dimensionality reduction	68.86 ± 1.82
Experiment 3: RF + Feature engineering	70.11 ± 4.76
Experiment 4: RF + Dimensionality reduction + Oversampling	72.80 ± 4.91
Experiment 5: RF + Feature engineering + Oversampling	74.06 ± 4.53
