Trial Outcomes & Findings for Effects of Aromatase Inhibition Versus Testosterone in Older Men With Low Testosterone: Randomized-Controlled Trial. (NCT NCT00104572)
NCT ID: NCT00104572
Last Updated: 2018-11-06
Results Overview
bone mineral density lumbar spine for all arms testosterone gel, anastrozole and placebo
COMPLETED
PHASE2
44 participants
1 year
2018-11-06
Participant Flow
The study randomized 44 subjects, however 9 of them stop the study before having the second visit completed, so we started the analysis with 35 subjects. The participant flow module has 35 subjects, because these subjects have a baseline and 3 months endpoints.
