The advantage of the net risk test approach
The advantage of the net risk test approach is that it reduces the likelihood that potential direct benefits from one intervention will be used as a justification for exposing participants to risks from unrelated interventions that offer no direct benefits. However, neither approach eliminates the need for subjective determinations. The net benefit test dispenses with clinical equipoise entirely, instead relying on a general principle of avoiding ‘excessive risk’. Whether a particular mix of risks and potential benefits is ‘reasonable’ or ‘excessive’ is ultimately left to the judgment of those charged with reviewing the study) (Coleman, 2021)
