  1. Shapiro-Wilk test was used to test the normality of data. Continuous variables were expressed as mean ± standard deviation in cases of normal distribution, and as median and interquartile range in cases of non-normal distribution. Normally distributed data were compared among groups using one-way ANOVA, and non-normally distributed data were compared among groups using Kruskal-Wallis test. BMD, bone mineral density; VAS, visual analogue scale; WA, wedged angle; KA, kyphotic angle
