Readers are radiologist 1 (R1), radiologist 2 (R2), and the algorithm (Alg). Means (95% confidence intervals) [°]. Statistical analysis was performed by repeated measures ANOVA followed by pair-wise Tukey's post-hoc test. Results of the other methods of determining femoral (according to the Reikeras, Tomczak, and Murphy methods) and tibial torsion (according to the bimalleolar and talus methods) are detailed in Supplementary Table 2. Adjusted p-values with significant differences indicated in bold type.
