Fig. 2: Proximal femoral shape variance among living humans by osteoporosis and intracapsular hip fracture.
From: Evolutionary roots of the risk of hip fracture in humans
a Between-group PCA of recent humans with and without an intracapsular hip fracture (ICHF), by osteoporosis diagnosis obtained from the DEXA scores (N = 59). The non-osteoporotic ICHF group can be distinguished from the other groups along PC1. b Heatmap and dendrogram created from the average Procrustes distances of individuals belonging to the same group from the mean shape of each group. c The surface distance of the mean shape of each group from the mean shape of the control group (non-osteoporotic, not fractured) represented by colors (blue for the lowest differences and red for the largest differences).
