Evaluation of the machine learning model 2 (ANB + Wits). 3-I: different models were tested (RF, KNN, SVM, LDA, CART, GLM), The X-axis shows the Accuracy and Kappa scores (95% confidence interval), for each model. 3-II: sensitivity and specificity of the best fitting model 2 (SVM) in diagnosing skeletal class I and II. The X-axis shows the class prediction, and the Y-axis shows the number of identified patients in each classification
