Fig. 5

Boxplots illustrating the distribution of errors (°) between deep learning (DL)-predicted and ground truth spinopelvic mobility angles. Mean Absolute Error ± SD values are displayed inside each boxplot (n = 2,524 X-ray images from 1,609 THA procedures). (a) All positions pooled. (b), (c), and (d) represent pelvic tilt (PT), sacral slope (SS), and lumbar lordotic angle (LLA), respectively, subdivided by X-ray functional positions: Stand, Step-up, and Seated. Significance: * (p < 0.05), ** (p < 0.01), *** (p < 0.001), **** (p < 0.0001).
