Frazier and Mosteller assert that medical research could be improved by a move toward larger, simpler clinical Line trials of medical treatments. Currently, (5) 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 (10) analysis. Although(让步,强调后半句) 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 (15) from research, would still be small in most studies. Only in research on entirely new treatments are new and unexpected variables likely to arise. FM认为药物研究可转为药物治疗的临床尝试,risk总是或多或少的存在
Frazier and Mosteller propose not (20) 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 (25) 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 (30) 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 (35) 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 (40) disease. Patients’ ages may also affect a treatment’s efficacy.
FM建议不只是研究个案而是要更多的临床的病人,扩大研究范围使得更有效 -------------------------------------------------------------------------------- According to the passage, Frazier and Mosteller believe which of the following about medical research? - It is seriously flawed as presently conducted because researchers overlook facts that are relevant to the subject of their research.
- It tends to benefit certain subgroups of patients disproportionately.
- It routinely reveals new variables in research on entirely new treatments.
- It can be made more accurate by limiting the amount of information researchers collect. (是方式不是准确性)
- It cannot be freed of the risk that significant variables may be overlooked.
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.
-------------------------------------------------------------------------------- The author mentions patients’ ages(line 40) primarily in order to 举例作用题为了说明上下文论证的观点,所以一般找它前面的那句话 - identify the most critical variable differentiating subgroups of patients
- cast doubt on the advisability of implementing Frazier and Mosteller’s proposals about medical research
- indicate why progressive diseases may require different treatments at different stages
- illustrate a point about the value of enrolling a wide range of patients in clinical trials
- substantiate an argument about the problems inherent in enrolling large numbers of patients in clinical trials
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 -------------------------------------------------------------------------------- The passage is primarily concerned with - identifying two practices in medical research that may affect the accuracy of clinical trials
- describing aspects of medical research that tend to drive up costs
- evaluating an analysis of certain shortcomings of current medical research practices
- describing proposed changes to the ways in which clinical trials are conducted
- explaining how medical researchers have traditionally conducted clinical trials and how such trials are likely to change
