Table 5 Correlation coefficient analysis of spinal muscles, age and spinal alignment parameters. SMM; skeletal muscle mass, TK; thoracic kyphosis (T5–12), LL; lumbar lordosis (T12–S1), SS; sacral slope, PI; pelvic incidence, PT; pelvic tilt, SS; sacral slope, SVA; sagittal vertical axis, PS; Psoas. *p < 0.05, **< 0.01, ***< 0.001 indicates significant differences between groups

From: The correlation analysis between sagittal alignment and cross-sectional area of paraspinal muscle in patients with lumbar spinal stenosis and degenerative spondylolisthesis
