Figure 3
Frequency of sclerosis per region for different anatomical forms (%). Upper row: ventral portion of the joint (regions 1–8). Middle row: middle portion of the joint (regions 9–16). Lower row: dorsal portion of the joint (regions 17–24). Columns represent anatomical types. Frequencies smaller than 5% are given in white boxes, frequencies of 5 to 10% are given in light red, frequencies above 10% are given in dark red boxes. Significantly higher frequencies (compared to both other groups using Chi-squared tests) are marked with asterisks: *p < 0.05/**p < 0.001.
