Scatterplot, linear regression line, and ROC curve from the SHUB registry. A Overall distribution of HU values at each of four lines according to T-scores; B linear regression lines showing the association between the HU value at each of the four lines and the T-score; C linear regression line showing the association between the T-score and mean skull HU; D ROC curve to determine the optimal cut-off skull HU values for predicting osteopenia and osteoporosis. ROC = receiver operating characteristic; SHUB = skull Hounsfield unit and bone mineral density; HU = Hounsfield unit
