Bland-Altman plots showing to differences (y-axis) and mean values (x-axis), in pelvic tilt, right hip and right knee. a: The mean difference of pelvic tilt and 95% confidence interval of the difference was − 0.5 (− 1.5 to 0.5) b: The mean difference and 95% confidence interval of the difference of right hip flexion/extension range was − 2.8 (− 3.9 to − 1.8). The horizontal line above and below the mean are 1 standard deviation. c: The mean and 95% confidence interval of the difference of right flexion/extension range was − 0.24 (− 1.2 to 0.7). The mean difference and 95% confidence interval of the difference of right hip flexion/extension range was − 2.8 (− 3.9 to − 1.8). The horizontal line above and below the mean are 1 standard deviation
