Best-performing 2.5% of the fits for the 2,054 mechanical stimulus candidates to experimentally observed UHMWPE wear (1,027 each for conventional and crosslinked UHMWPE). The tabulated quality of fit Q is the average of three measures: (1) 2-D correlation coefficient r, (2) fraction of shared area  in normalized plots of the two given datasets, and (3) correlative statistic R² from a fixed/random effects ANOVA statistical model (See Appendix A). The complete rank list is provided in Appendix B (page 30). Please refer to the key following table for abbreviations.
