Figure 4.
ROC curves discriminating horses with left forelimb (LF) lameness from sound horses; and discriminating horses with right forelimb (RF) lameness from sound horses, plotted for each sensor location (head, withers, pelvis); and plotted for asymmetry indice: AI-min (blue), AI-max (red), AI-up (black) and AI-down (cyan). The best specificity and sensitivity point of each curve is represented by a circle. The dashed black line is the hypothesized ROC curve with discrimination capacity only due to perfect chance.
