 Critics respond that even when clinical equipoise obtains for the population of patients, the specific circumstances of individual patients within that population might imply that one of the treatments under investigation is better for them (Gifford 2007). A specific patient may have reduced liver function which places her at greater risk of harm if she receives a treatment metabolized by the liver. And some patients may have personal preferences which incline them toward one treatment over another (e.g., they may prefer a one-time riskier procedure to multiple, lower risk procedures which pose the same collective risk). Current debate focuses on whether randomized clinical trials can take these possibilities into account in a way that is consistent with the norms of clinical medicine.
