The symbol • indicates the presence of the bone curvature region variable in the model. In1, Age; In2, Body mass index; In3, Lateral trochlea; In4, Lateral central condyle; In5, Lateral posterior condyle; In6, Lateral tibial plateau; In7, Medial trochlea; In8, Medial central condyle; In9, Medial posterior condyle; In10, Medial tibial plateau. Model (M)20-13-6, the best model with five bone curvature region variables; M20-13-6-1 to M20-13-6-5, the model with four variables. R, correlation coefficient; RMSE, root mean square error; MAE, mean absolute error.
