Effects of 18 Months of Growth Hormone Replacement Therapy on Bone Mineral Density in Patients with Adult Growth Hormone Deficiency: A Retrospective Study

Figure 4

Differences between different Z-scores’ groups in percentage change in BMD. (a) Changes in lumbar spine BMD over an 18-month treatment period; (b) changes in total hip BMD over an 18-month treatment period; (c) difference in change between different Z-scores’ groups in lumbar spine BMD at the 18^th month. for the Z < −1 group compared with the Z ≥ −1 group (Mann–Whitney U test); (d) difference in change between different Z-scores’ groups in total hip BMD at the 18^th month. for the Z < −1 group compared with the Z ≥ −1 group (Mann–Whitney U test). The results are presented as the mean ± SE.
