score values, an obvious decrease tendency with increasing age, both at the<br />
vertebral column and at the hip bone, which is consistent with the decrease in the<br />
bone mineral density that comes with age (Fig. 1.A).<br />
Fig. 2. The regression between the BMD determined at the hip bone and the BMD<br />
determined at the vertebral column in all cases. According to the values of the correlation<br />
quotient there is a not very tight connection between the bone mineral density<br />
determined at the hip and at the vertebral column.<br />
On the other hand, the Z-score, which also takes into account the patient’s age,<br />
has a tendency of increasing with age, both in the case of the vertebral column, and in<br />
that of the hip bone (Fig. 4). This also explains the correlation quotient’s greater<br />
values, as compared with the previous situation. Thus, in what concerns the regression<br />
between the Z-score and age, we noticed that age explains 27.26% of the Z-score<br />
variability at the vertebral column (R 2 = 0.2726, p
