Indicators like biomarkers that predict a clinical benefit, even if they aren't the benefit themselves. 4. The Ethics of Equipoise
Blinding (or masking) prevents the "placebo effect" or observer bias from creeping into the data. The patient doesn't know their treatment. Fundamental Concepts for New Clinical Trialists
The main question the study is powered to answer (e.g., "Does this drug lower blood pressure?"). Indicators like biomarkers that predict a clinical benefit,
We don’t randomize just to be fair; we do it to eliminate . Randomization ensures that both known and unknown factors (like genetics or lifestyle) are distributed evenly across groups. This allows us to say with confidence that any difference in outcomes is due to the intervention, not the baseline characteristics of the patients. 2. Blinding: Protecting the Data’s Integrity The patient doesn't know their treatment
This is the moral compass of clinical trials. is the genuine uncertainty within the medical community about which treatment is better. If we already know for a fact that Treatment A is superior to Treatment B, it is unethical to start a trial. We only experiment when there is a true "honest doubt" to resolve.
