Table 1 Reliability of All Measurements

From: 3D simulation of radiographic projections to test and reduce the effect of pelvic tilt on the accuracy of cross-table lateral radiography

  ICC for Intra-Observer (95% CI) ICC for Inter-Observer (95% CI)
PT 0.962 (0.946 to 0.987) 0.933 (0.899 to 0.963)
VCL 0.938 (0.891 to 0.963) 0.923 (0.897 to 0.941)
VCL3D 0.953 (0.935 to 0.968) 0.962 (0.946 to 0.987)
VCT0 0.982 (0.968 to 0.989) 0.936 (0.916 to 0.958)
VCT1 0.948 (0.968 to 0.989) 0.925 (0.889 to 0.953)
  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
