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."

In this argument, the author suggests that patients should take antibiotics for their muscle treatment, because the preliminary results can proved it by studying of two groups of patients. However, the author can not provide any useful information to make us believe that this study has reliability.
First, the author can not refer about any background of two groups of patients. We know that different patients have different symptom, which should be treaded by different measure. If the first group had litter muscle injure than the second, of course, the first's recuperation time is less than the later. If the first group was young men, and the second group was old women, no problem young men spend less time in recuperation than women. If so, we should consider whether the author's suggestion should be believed.
Secondly, if we admitted that the two groups of patients had same situation on muscle injuries, but there is no message about the measure of the two doctors. Maybe Dr. Newland uses a special measure to cure his patient, which has more effect than antibiotics. In this case, how can say that the antibiotics play an important role in rule muscle injuries? Or maybe Dr.Alton does not use prefer method to cure his patient, how can we complain about no use antibiotics? If the assumptions came true, the mere fact can not provide that the viewpoint of author is meaningful.
Third, if we accepted that the two doctors use same measure to cure their patients, and using or not antibiotics has different results, the author can suggests that all patients who are diagnosed with muscle strain should take antibiotics in their treatment. At first glance, the author provides a good idea for doctor and patient, but after considering seriously, we should find some problems. If the patient would not be treated with antibiotics, accepting author's suggestion, the patient may recover slowly, or even goes to bad situation. Or if using more antibiotics would create negative effects, such as felt allergy, comatose and so on. Without considering and ruling out those influent situations, the author can not claim using antibiotics can treat muscle injured patient recuperate quickly.
In conclusion, the author should provide enough useful messages about antibiotics' function in this situation excepting influential elements. But the author of this argument fails to do this. |
