In the GH-secreting pituitary adenoma group, BMD was significantly elevated at the L1, L2, femoral neck, Ward triangle, trochanter, femoral shaft, and total hip sites compared with the corresponding values in patients with nonfunctioning adenomas (p=0.006, 0.032, 0.001, 0.036, 0.005, 0.037, and 0.008, respectively). Here, GH1 is linked to pituitary gland adenoma.
