Fig. 6From: Cup implantation accuracy using the HipCOMPASS mechanical intraoperative support deviceCup implantation errors in the COMPASS and non-COMPASS groups are shown in a scatterplot. The COMPASS group contained one outlier (error greater than 10°) out of 97 patients (1.0 %), whereas the non-COMPASS group contained 39 outliers out of 80 patients (48.8 %); i.e. the COMPASS group contained significantly fewer outliers (p < 0.001)Back to article page
