Fig. 9. The percentage of cortical bone mineral densities (cBMDs) of HAC dogs compared with that of normal dogs. Linear regression equations obtained from scatter plots of normal BMDs were used to see if BMDs of HAC dogs were actually lower than those of normal dogs at the same ages, assuming normal values are 100%. The predicted age-adjusted cBMDs of PDH patients were about 10% reduced and rather to be increased at L6 vertebra. However, the cBMDs of ADH patients were approximately 60% lower than those of normal dogs, and the difference between ADH and PDH patients at this site was quite evident.
