Curve of mean (± standard deviation) interpolated data of the 3D tilt. (a 1-2): 3D tilt of the sagittal plane; (b 1-2): 3D tilt of the axial plane; (c 1-2): 3D tilt of the coronal plane; (a 2-c2): 3D tilt was normalized to the full extension. The trends of 3D tiltsagittal were different between the two groups (P = 0.020). The trends of 3D tiltsagittal normalized to the full extension were consistent between the two groups (P = 0.285). The trends of 3D tiltaxial were different between the two groups (P = 0.018). The trends of 3D tiltaxial normalized to the full extension were consistent between the two groups (P = 0.448). The trends of 3D tiltcoronal and 3D tiltcoronal normalized to the full extension were consistent between the two groups (P = 0.628, P = 0.669, respectively)
