TOPIC: 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 the argument, the author concludes that all patients diagnosed with muscle strain should be suggested to take antibiotics. Careful examination of the study the author cited to support the argument, however, reveals that it lends little credible support to the conclusion.
Firstly, as the argument mentioned, the study is a preliminary one so the conclusion is not convincing. Perhaps the further research will overturn the current conclusion. In addition,it's unclear that whether there is a selection bias in the sample of the study. The author fails to inform us other factors of the two groups which influence the recuperation time, such as age and the severity degree of the muscle strain. It 's entirely possible that the average age of the
second group is older than the first group so they undergo a longer process of healing. At such circumstances, antibiotics should not be considered as the main reason of the healing differences between two groups.
Secondly, even if the factors about the patients are the same between the two groups, the doctors can also cause the deference of recuperation time. Different doctors have different experiences and provide different treatments. The doctor of the first group is a specialist in sports medicine as the argument mentioned while the doctor of the second group is a general physician. Common sense tells us that the first doctor should be better at curing muscle strain than the second one which attributes to the shorter recuperation time. If he is famous among the patients and the study let the patient choose their doctor freely , this effect will further undermine the conclusion.
Finally, in asserting antibiotics should be a part of the treatment for muscle strains, the arguer overlooks the negative effects that antibiotics might have. Regular intake of antibiotics might result in drug resistance and some people may be hypersensitive. So it is too hasty for the arguer to recommend all the patients to take antibiotics.
In sum, the argument is logically flawed and therefore unconvincing. To bolster the conclusion, the author should provide more details about the study including the sample selection, the difference of treatments offered by the two doctors. What’s more further research should be conducted to study the effect of antibiotics for muscle strains. |
