TK indicates thoracic kyphosis; SS Sacral slope, PT Pelvic tilt, TPA, T1 pelvic angle, SVA Sagittal vertical axis, PI–LL Mismatch of pelvic incidence minus lumbar lordosis, SAA Sagittal acetabular anteversion, PFA Pelvic femur angle
^aLinear regression analysis showed significant correlation changes in all spinopelvic parameters and lumbar lordosis; N/A = not applicable; ^b The coefficient refers to the 1° increase in lumbar lordosis that would result in changes in each parameter.
