In the aspirin trial, what are treatments?

Aspirin and placebo.

Treatments are the interventions being compared in a trial. In the aspirin trial, the two interventions are taking aspirin and taking a placebo (a pill that looks like aspirin but has no active drug). The placebo helps control for the placebo effect so any difference in outcomes can be attributed to aspirin itself.

The other options describe outcomes (heart attack vs no heart attack), the population studied (men aged 50–84), or a general regimen description (daily pill vs no pill) rather than the actual interventions being tested.

Daily pill vs no pill.

Heart attack vs no heart attack.

Men aged 50-84.
