Figure 3 (A) Relation between CAGE  20 scores (Y-axis) and total calcium scores (X-axis) independent from either risk factors or radionuclide perfusion scores. The plot shows the residuals from regressing cardiac risk factors and radionuclide perfusion scores against CAGE 20 scores and residuals from regressing cardiac risk factors and radionuclide perfusion scores against total calcium scores. The scales are comparable with those in Figure 2, because unstandardized residuals were used. Negative values are a result of predictions with lower values than actual observations, and positive values are a result of predictions greater than actual observations. (B) Independent relation between CAGE 50 scores (Y-axis) and total calcium scores (X-axis). The residuals from regressing cardiac risk factors and radionuclide perfusion scores against CAGE 50 scores (Y-axis) and the residuals from regressing cardiac risk factors and radionuclide perfusion scores against total calcium scores are shown. The explanations provided for (A) also apply here.
