3 Fig. 2 A comparison of (-) control and (--) OA mean values of FDs calculated for the (a) medial and (b) lateral compartments over all trabecular sizes 0.2–1.1mm (paired samples t tests, P<0.05). Boxes denote the mean value and whiskers are the SD value. Osteoarthritis and Cartilage  , DOI: ( /j.joca ) Copyright © 2007 Osteoarthritis Research Society International Terms and Conditions

4 Fig. 3 A comparison of (-) control and (--) OA mean values of the fractal signatures calculated for the (a,c) medial and (b,d) lateral compartments in the horizontal (HD) and vertical (VD) directions, respectively. Asterisks denote statistically significant differences (paired samples t tests, P<0.05) at individual trabecular image sizes.
