Box and whisker plot illustrating the difference ΔPelvicPosition and ΔDefinition for the three cup inclination groups (Unacceptable – low; Acceptable and Unacceptable – High). The range of ΔPelvicPosition is much greater (−13° to + 16°) than the range of ΔDefinition as seen in graph (0 to + 13°) amongst all groups
