Comparison of majority classification (≥ 18 years) performance between the current work and other studies using automated and MRI-based methods. Besides accuracy, sensitivity, and specificity the area under the curve (AUC) represents the capacity of a model to discern between minors and adults. Metrics are presented in percentage. An overview of the population, datasets, and methods of the studies can be found in Table 3

Study	Minors	Accuracy	Sensitivity	Specificity	AUC
