  1. mean + SE Mean value ± standard error, 95% CI 95% confidence intervals, BMI body mass index was calculated as the weight in kilograms divided by the square of the height in meters (kg/m2), SRS-22r Scoliosis Research Society – 22r Outcome Measures [25, 26] #1: Pearson’s chi-square test (X2) was used to test for sex difference. All the parameters except sex were compared using analysis of variance analysis followed by a post-hoc test (Tukey-Kramer’s HSD)
