Cartilage thickness. (a) Mean cartilage thickness D (solid) ± standard deviation (dashed) for all samples at each age. (b) Mean cartilage thickness D as a function of age for hind legs (solid) and fore legs (dashed). The model predicts significant differences for: 'x' - fore leg > hind leg. (c) Mean cartilage thickness D as a function of age for lateral site (solid) and medial site (dashed). The model predicts significant differences for: 'x' - lateral site > medial site. (d) Mean cartilage thickness D as a function of age for the caudal site (solid), distal site (dashed) and rostral site (dotted). The model predicts significant differences for: 'x' - rostral site > caudal site, '+' - distal site > caudal site, '*' - distal site > rostral site, and ' ◇ - rostral site > distal site.
