In the metric names, ‘0’ corresponds to the healthy class, and ‘1’ represents the disordered. PR, RE and F1 represent Precision, Recall and F1 score respectively. The mean values over folds are presented for all matrices. The highest accuracy is indicated in bold. Additionally, standard deviations for accuracy are provided
