graph illustrating the estimated (black straight lines) spontaneous variation over time and the 95% confidence interval upper (dark grey dashed lines) and lower (light grey dashed lines) limits of the anteroposterior interphyseal angle (AP-IPA: Fig. 2a), the lateral interphyseal angle (L-IPA: Fig. 2b), the limb length discrepancy expressed as percentage shortening, as compared with the opposite side (LLD%: Fig. 2c), and as crude length (LLDcm: Fig. 2d)
