Figure 3From: Identification of hip fracture patients from radiographs using Fourier analysis of the trabecular structure: a cross-sectional study Scree plot. Example of a scree plot from the perpendicular profile. The first component typically accounts for the largest amount of variance. The components are chosen to the left of an 'elbow' in the plot. Here components 1 to 5 are included in the analysis as they lie before the 'elbow' at point6 (eigenvalue = 1.63).Back to article page
