Results of post hoc tests on GOH model’s $\mathit{\kappa }$ (collagen dispersion). a Effect of age on collagen dispersion of the uninjured subgroups. Age-dependent effects of injury on collagen dispersion within: b the mature group, c the aging group, and d the aged group. Collagen dispersion reduced with age (a) and with injury except in the aging group (c) and in the aged group, which exhibited neither statistical significance nor trend with injury. Data are presented as mean ± standard error. Significance is denoted by: *** ($p<0.001$), ** ($p<0.01$), and * ($p<0.05$)
