Performance in the test split of the RF model in the five-class study. Results in more detail are found in Supplementary Table S10. 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	60.37 ± 2.93
Experiment 2: RF + Dimensionality Reduction	61.25 ± 4.39
Experiment 3: RF + Feature engineering	64.01 ± 2.25
Experiment 4: RF + Dimensionality reduction + Oversampling	60.38 ± 3.12
Experiment 5: RF + Feature engineering + Oversampling	67.31 ± 3.93
