To evaluate the changes in BMI, flexibility, perimetry, XSD, YSD and displacement area over time, an analysis of variance with repeated measurements was performed. The assumptions of circularity of variances and the covariance matrix were verified through the Mauchly test. When this assumption was not satisfactory, the correction was performed by the Huynh-Feldt test 21 . The assumption of normality was assessed through the construction of a normal probability plot of residuals.
In the VAvg analysis, the non-parametric Friedman method was utilized. Initially, the technique of variance analysis with repeated measurements was utilized. However, according to the residual distribution analysis, deviations from the normal distribution required the use of a non-parametric technique.
Correlations between the BMI variation at 6 and 12 months after surgery and flexibility and balance were assessed using Spearman's correlation coefficient 22 .
Significance was determined to be 0.05.
The analyses were performed with the aid of
Minitab (version 16) and
SPSS (version 18) software.
