Mean ± SE percentage change from baseline in serum C-telopeptide concentrations, L4 trabecular BMD by quantitative CT, lumbar spine BMD by DXA, and femoral neck BMD by DXA according to testosterone dose (A, C, E, and G) and testosterone levels (B, D, F, and H). P values for tests of dose-dependent linear trends for each measure are at the top of each panel. Men in Group 5 received either 7.5 or 10 g/day. *Denotes groups that are significantly different from the control group using Duncan’s multiple range test.
