Figure 7.

Computed HIC₁₅, RIC₃₆, and BrIC for each of the ground truth (GT) and the three approximated data sets: PCA, triangle (Tri), and half-sine (HS). The circles represent each sample, the solid red line represents the mean, and the blue and red regions show the standard deviation and standard error, respectively. The solid blue and dashed red lines represent 50% risk of concussion and skull fracture, respectively. Significant differences are indicated with (*) for p < 0.01. HIC and RIC graphs are on log-scale.
