In these scatterplots, the relation between thoracic Cobb angle in the upright, prone (red trend line), and supine (blue trend line) positions is shown. Although the upright Cobb angle was significantly larger, significant linear correlations were found (ICC 0.967; P < 0.001), indicating that with increasing Cobb angle, differences between the body positions increased simultaneously
