Sagittal parameters were obtained on the whole spinal lateral radiograph. Spinal parameters include thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), and lumbar lordosis (LL). Pelvic parameters include pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). Hip parameters include pelvic rotation (PR) and hip inclination angle (HIA). Spine\u2010pelvic parameter is spino\u2010sacral angle (SSA). Sagittal balance parameter is sagittal vertical axis (SVA). PI\u2010LL, PT, SVA, HIA, and TLK were regarded as primary results, and the others were secondary outcomes. The independent sample <jats:italic>t<\/jats:italic>\u2010test was used to compare gender. Pearson correlation analysis was used to evaluate the correlation between primary results and secondary results.
