Table 5.

Linear regression analysis: 1. Correlation between measurements of average mandibular body growth of each patient on CBCT (independent variable, Δ_3D Go–ME) and RLCs (dependent variable, Δ_2D Go–Me). 2. Correlation between transverse and sagittal growth of the mandible (independent variable, ratio of ΔBO to ΔAO) and error of bi-dimensional radiographs RLCs in the evaluation of mandibular growth compared with CBCT scan (dependent variable, ΔGo–Me3D – ΔGo–Me2D).
