| Asymmetric ratio of HU by concave/convex | 1.23±0.14 | 1.19±0.11 | 1.25±0.15 | 0.105 |
| Plus–minus values are means±SD; * In age group, BMI group, apex orientation, and apex vertebrae group, -values are the results of chi-square tests or Fisher’s exact tests. In age, BMI, Cobb angle, asymmetric ratio of height by concave/convex, and asymmetric ratio of HU by concave/convex, -values are the results of Students’ t-tests. BMI – body mass index; HU – Hounsfield units. | ||||
