Table 3 Pearson correlation analysis of spinopelvic parameters and concave or convex LMA at the upper or lower intervertebral level of the apical vertebra

From: Correlation between multifidus muscle atrophy, spinopelvic parameters, and severity of deformity in patients with adult degenerative scoliosis: the parallelogram effect of LMA on the diagonal through the apical vertebra
