题目信息

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.

According to the passage, Frazier and Mosteller believe which of the following about medical research?

A:It is seriously flawed as presently conducted because researchers overlook facts that are relevant to the subject of their research.

B:It tends to benefit certain subgroups of patients disproportionately.

C:It routinely reveals new variables in research on entirely new treatments.

D:It can be made more accurate by limiting the amount of information researchers collect.

E:It cannot be freed of the risk that significant variables may be overlooked.

正确答案： E:It cannot be freed of the risk that significant variables may be overlooked.

f和m认为以下关于医学研究的说法哪个是对的？
A.现在进行的医学研究方式是有缺陷的，因为研究者忽视了和研究主题相关的事实。（他们认为研究者的问题不在于忽视了事实，而是纳入了过多个体的不相关因素，但是考虑的群体范围又不够大,所以造成了缺少代表性） 
B.研究倾向于对某些不成比例的特定群体的病人。（现在的研究根本没有考虑不同群体的病人，而是只想研究单一有这个疾病的病人，却不在乎他们内部的不同，比如说不同年龄）
C.研究通常揭露新的变量（没提到）
D.要是限制研究者收集的资料的量，研究会更加准确（文中不是单一说收集的资料要小，而是说内容要有针对性，但是群体要广）
E.正确。没办法避免一些有效的变量可能被忽视（对应文章的一句话 such risk, never entirely eliminable from research）
