When Are Research Risks Reasonable In Relation To Anticipated Benefits?, Charles Weijer, Paul Miller
When Are Research Risks Reasonable In Relation To Anticipated Benefits?, Charles Weijer, Paul Miller
Charles Weijer
The question "When are research risks reasonable in relation to anticipated benefits?" is at the heart of disputes in the ethics of clinical research. Institutional review boards are often criticized for inconsistent decision-making, a problem that is compounded by a number of contemporary controversies, including the ethics of research involving placebo controls, developing countries, incapable adults and emergency rooms. If this pressing ethical question is to be addressed in a principled way, then a systematic approach to the ethics of risk in research is required. Component analysis provides such a systematic approach.

It is widely believed that baseline imbalances in randomized trials must necessarily be random. In fact, there is a type of selection bias that can cause substantial, systematic and reproducible baseline imbalances of prognostic covariates even in properly randomized trials. It is possible, given complete data, to quantify both the susceptibility of a given trial to this type of selection bias and the extent to which selection bias appears to have caused either observable or unobservable baseline imbalances. Yet, in articles reporting on randomized trials, it is uncommon to find either these assessments or the information that would enable a …
