Sagittal parameters of idiopathic scoliosis patients with non-progression, moderate progression, and severe progression of thoracic curve (°, X ± S)

Group	Thoracic kyphosis angle	Lumbar lordosis Cobb’s angle	Sacral slope Cobb’s angle	Pelvic incidence Cobb’s angle	Pelvic tilt angle
Non-progression	18 ± 6	51 ± 7	35 ± 6	42 ± 9	8 ± 6
Moderate progression	14 ± 5a	46 ± 9	36 ± 7	45 ± 11	9 ± 7
Severe progression	9 ± 4ab	50 ± 8	38 ± 6	46 ± 9	8 ± 7

^aP < 0.01, compared to the non-progression group; ^bP < 0.05, compared to the moderate progression group.
