Frazier and Mosteller assert that medical research could be improved by a move toward larger, simpler clinical trials of medical treatments. Currently, researchers collect far more background information on patients than is strictly required for their trials-substantially more than hospitals collect-thereby escalating costs of data collection, storage, and analysis. Although limiting information collection could increase the risk that researchers will overlook facts relevant to a study, Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies. Only in research on entirely new treatments are new and unexpected variables likely to arise.

Frazier and Mosteller propose not only that researchers limit data collection on individual patients but also that researchers enroll more patients in clinical trials, thereby obtaining a more representative sample of the total population with the disease under study. Often researchers restrict study participation to patients who have no ailments besides those being studied. A treatment judged successful under these ideal conditions can then be evaluated under normal conditions. Broadening the range of trial participants, Frazier and Mosteller suggest, would enable researchers to evaluate a treatment's efficacy for diverse patients under various conditions and to evaluate its effectiveness for different patient subgroups. For example, the value of a treatment for a progressive disease may vary according to a patient's stage of disease. Patients' ages may also affect a treatment’s efficacy.

从文中意思可知:研究者一般搜集过多的无关信息,增加了数据搜集的成本,并且研究病人的样本很有限
A正确,说明了上述第一点
B错误,与“数据精确性”无关
C错误,“忽略一些变量”不会增加研究成本,与原文相反
D错误,文中没有提及“他们忽略了那些与他们研究相关的因素”
E错误,与“医院使用过的方法”无关

    A. 原文 Currently, researchers collect far more background information on patients than is strictly required for their trials. 研究者收集了比需要多的信息,所以收集了一些无关信息,正确

    C项,researcher generally conduct trial(会收集很多无关的信息,这样做)能够避免(忽略对研究结果有影响的变量的)风险,即使这样做会提高成本。解析错误。关键词是avoid,原文说风险never entirely eliminable。

    Currently, researchers collect far more background information on patients than is strictly required for their trials. 研究者收集了远超所需的信息--收集了一些无关信息
    这个可以直接推论,不算过度推理

    c的定位是这句:Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies.

    减少信息导致risk增加 不能说明原来的risk的情况 他原来是否存在也无从得知
