Global summary plots representing the average of the importance and the contribution of features in the learning of the CatBoost regressor model to predict the values of the self-rated oral sensitivity in control individuals (a) and in patients with chemosensory loss (b). The Y axis represents the order of the features’ importance, while the average contribution to the model output is represented in the X axis. The numbers next to each bar represent the mean values of the contribution of features.
