Overview of the process used for analysing differences in cartilage stress distributions between men and women for jar twist. Cartilage stress distributions were normalized by peak stress (A). Principal Component Analysis (PCA) was performed on the set of normalized distributions (B) to produce PC modes and weights. Linear Discriminant Analysis (LDA) of PC weights classified sex differences (C). LDA weights were used to reconstruct classification criteria for men and women (D). Red indicates a high probability of contact, and blue indicates a low probability.
