Significance level: p < .05. Not all parameters were available for all patients: ID-ASD maximal coronal Cobb angle n = 21; ID-ASD sagittal parameters n = 23; DN-ASD maximal coronal Cobb angle n = 18; DN-ASD sagittal parameters n = 26. ID-ASD, symptomatic idiopathic scoliosis-adult spinal deformity; DN-ASD, “de novo” scoliosis-adult spinal deformity.
