TABLE S1. Hip and knee angles in Uner Tan syndrome cases, healthy in-diviuals and perimates during standing on all fours

Univariate ANOVA results with Means, SD, 95% confidence interval (CI), and Bonferroni group comparisons of the hip and knee angles during quadrupedal standing in the five study groups.Group 1. UTS (cases with Uner Tan syndrome)Group 2. Req. QL (healthy individuals with requested quadrupedal locomotionGroup 3. Primates1 (terrestrial primates)Group 4. FREE QL (individuals with free quadrupeal locomotion)Group 5. Primates2 (arboreal primates on trees)Group 6. Primates3 (arboreal primates on the even ground)Group 1-2: difference between Group1 and Group2D: difference***: p < .000
