题目
Argument51 The following appeared in a medical newsletter.
"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."
翻译:
医生长期以来怀疑严重肌肉扭伤后的二次感染妨碍了一些患者迅速康复。这一假说现在被一项对两组患者的研究的初步结果所证实。第一组患者全部由专攻运动医学的Dr. Newland治疗肌肉损伤,他们在疗程中经常服用抗生素。他们的康复期平均比通常预期的快40%。第二组患者由综合医师Dr. Alton治疗,他们被给予糖丸,而患者相信他们在服用抗生素。他们的平均康复时间没有明显缩短。因此,任何被确诊为肌肉损伤的患者应被建议服用抗生素作为辅助治疗。
**********************************************************
提纲
(1)假说的证明需要大量的试验和研究,仅凭一次比较是不够的。而且也没有给出两组患者的具体情况,也许第一组患者的情况都比较好。
(2)康复期的平均数不能说明问题,也许第一组大部分患者康复时间比较长,个别人时间很短,而第二组大部分患者康复时间比较短,个别人时间很长。
(3)即使第一组患者大部分都比第二组的康复时间快,但也不一定就是抗生素的作用,有可能因为两个医师的方法不同。
(4)即使抗生素真的有用,也不能给任何肌肉损伤的患者服用,因为有可能有很大的副作用,或者有些患者对抗生素过敏。

正文
In this argument, the arguer asserts that secondary infections can result in the slow heal after severe muscle strain by a study's preliminary result and suggests to prescribe antibiotics for all patients diagnosed with muscle strain. His assertion and suggestion seems reasonable and logical at first glance, but after careful examination, we can find out several flaws as follows.
First of all, any hypothesis, especially on medicine, needs lots of experiments and studies before being proved because it is the demand of science study and medicine has great influence to people's health. So it is too cursory for the arguer to declare the hypothesis has been proved only depending on preliminary results of a study of two groups of patients. Moreover, the arguer does not provide the detail information about the two groups of patients, such as the health condition, the degree of muscle injuries, and so on. If the patients of first group are in condition and only have slight muscle strain, then it is common that their recuperation time was short.
Secondly, the average recuperation time cannot be used as strong evidence because most patient's state cannot be gotten only from the average number. For example, if a few of patients heal very quickly, but most of the first group of patients spend relative long time before getting well, then it is still possible that the average recuperation time of the first group is 40% quicker than typically expected. Similarly, it is also suitable for the second group. If most patients of the second group get well quickly, but few of them spend too long time to heal, then the average recuperation time may seem long.
Thirdly, even if most patients of the first group get well quickly than most patients of the second group, it is not certain that it is antibiotics that make the difference. It is totally possible that Dr. Newland, the expert in sports medicine, is very familiar and experienced to deal with muscle strain and takes efficient treatments for the first group. However, the doctor who treats the second group is a general physician, and he may be not good at dealing with muscle strain.
Last but not the least, granted that antibiotics is really effective in treating muscle strain, the arguer should not give the suggestion because it is only the preliminary results. We are not sure whether taking antibiotics will have some side effect obviously or hiddenly, in addition, maybe some patients are hypersusceptible to antibiotics, which will bring serious result if let them take antibiotics.
To sum up, the arguer fail to give convincing evidence to support his assertion and suggestion, so he has to take the facets discussed above into accounts, that is, to find out the genuine reason for the difference of the two groups' recuperation time and to prove antibiotics will not bring any side-effect. |
