Effect of the angle the foot was presented to the camera on the performance in detecting the metatarsal footpad and the alteration. Data are presented as the number of feet in percent for the respective scores with increasing gray levels indicating an increasing score level (light gray = scoring level 0–dark gray scoring level 3; see Table 2 for the explanation of scoring levels); *p < 0.05; the number of feet for the detection of the metatarsal footpad: skew = 2,008, straight = 3,127; the number of feet for the detection of the alteration: skew = 1,996, straight = 3,119.
