GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov codeSource
Group 1Testosterone
Participants received 7.5 g of 1% testosterone gel to achieve a nominal delivery of 75 mg testosterone daily for 3 years. Dose adjustments were made by an unblinded observer. (Serum testosterone level measured on treatment day 15 was measured in a sample sent separately to the laboratory such that the results were reported directly to unblinded physician, who then communicated the decision about dose adjustment (or not) directly to the research pharmacist through e-mail.)
