  1. ICC, intraclass correlation coefficient. CI, 95% confidence interval. Mean (95% confidence interval). PT, pelvic tilt measured on lateral radiographs. VCL, version angle measured on CL radiographs. VCL3D, version angle measured on 3-D simulated CL radiographs under different actual VA and PT. VCT0, version angle measured on CT without adjusted the pelvic tilt. VCT1, version angle measured on CT which was converted into 3-D model and adjusted PT to the value measured on radiographs
