The means and standard deviations are given, followed by minimum and maximum in the brackets. IR – internal rotation, ER – external rotation. One way ANOVA was used for normal distribution, Kruskal-Wallis test for not normal. The values of the three columns do not differ significantly, apart from the absolute difference of the range of external rotation, signifying less asymmetry in Lenke V curves.
