If one views information about randomization as "relevant" in this sense, as Levine and Lebacqz do, then it becomes ethically obligatory to disclose the fact of randomization to potential subjects. Levine and Lebacqz suggest that arguments against such disclosure, such as those advanced by Chalmers (1967), depend on a different interpretation of the respect for persons principle and on a decision to assign a higher weight to beneficence or efficiency in contrast to respect for persons. One argument of Levine and Lebacqz is of special interest to us when they examine Chalmer's (1967) claim that knowledge of randomization would not be "material" to a patient's decision.

Crossing the topmost or bottommost lines indicates that a statistically significant result has been achieved for either A or B, respectively. Crossing the rightmost line indicates a failure to achieve statistical significance. Sequential trials do not eliminate the problem of reduced statistical efficency due to continuous monitoring of the data, though they do take this into account in the statistical calculations. Such trials make it possible to limit the harm a new substance or technique may cause and also may allow an efficacious new therapy to become accepted more quickly.
