Equipoise is an essential concept in the ethical conduct of clinical trials. It refers to the state of uncertainty about which treatment option is best for a particular patient. In order for a clinical trial to be ethical, there must be genuine uncertainty among experts in the field about the relative benefits and risks of the experimental treatment being studied.
This concept is important because clinical trials involve exposing patients to potential risks in order to gather scientific data. If there is a clear consensus among experts that one treatment is superior to another, it would be unethical to expose patients to the experimental treatment, as it would not be in their best interest. By contrast, if there is genuine uncertainty about the relative benefits and risks of the experimental treatment, it may be appropriate to offer patients the opportunity to participate in a clinical trial in order to help determine which treatment is most effective.
The principle of equipoise also requires that researchers ensure that the benefits and risks of participating in a clinical trial are fairly balanced. This means that researchers must carefully consider the potential harms and benefits of the experimental treatment, as well as the available alternatives, in order to ensure that the risks of participating in the trial are reasonable in light of the potential benefits.
In summary, equipoise is an essential principle in the ethical conduct of clinical trials. It requires that there be genuine uncertainty about the relative benefits and risks of the experimental treatment being studied, and that the risks and benefits of participating in the trial are fairly balanced. Without equipoise, it would be unethical to expose patients to the potential risks of participating in a clinical trial.

Wrong ethical foundation The equipoise requirement ensures that trials are conducted only when expert clinicians disagree about the relative merits of standard care and the investigational or control treatment, meaning that all treatments in a trial are consistent with competent clinical care. Note that factual evaluation contrasts benefits and risks of usual care versus the expected benefits and risks of the trial after pooling all arms, and that the decision point always comes before randomization and hence is independent of the relative expectations for the different arms of the trial.
