Table 1 Shows the different mean PI for hips with positive and negative parameters for acetabular retroversion. n (+/−), number of hips with positive or negative parameter; PI (+/−): respectively PI of positive and negative hips. STD is the standard deviation. Sig. is the p-value indicating whether the difference in mean PI was significant or not
