  • Randomised controlled trial
  • multicentre
  • double-blind
  • placebo-controlled
  • non-inferiority

Mean (±SD) treatment duration 21.7±14.1 months; mean follow-up 33.0±12.1 months

Authors' conclusion

In men with hypogonadism and preexisting or a high risk of cardiovascular disease, testosterone-replacement therapy was noninferior to placebo with respect to the incidence of major adverse cardiac events.

Study context

Population
Men 45 to 80 years with preexisting or high risk of CVD, symptoms of hypogonadism and two fasting testosterone levels <300 ng per deciliter
Participants
5,246 men
Comparison
Testosterone gel vs placebo gel
Primary endpoint
First MACE: CV death, nonfatal MI or nonfatal stroke (time-to-event)

Primary result

As reported in the abstract

Hazard ratio

0.96

95% CI 0.78–1.17

P < 0.001

Events by treatment group

Testosterone vs Placebo
HR 0.96 (95% CI 0.78–1.17); P < 0.001

Secondary outcomes

Sensitivity analyses (events censored at various times after discontinuation)

Similar findings

Secondary end point (CV death, nonfatal MI, nonfatal stroke or coronary revascularization) and each component of the primary end point

Incidence appeared similar in the two groups
