51.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."
The author of this argument asserts that secondary infections keep some patients from healing quickly after severe muscle strain. And to support his viewpoint he cites a experiment include two groups of patients who under different treatment condition. the argument and the evidence support it may applausive at first blush, however, it suffers from several critical flaws.
Firstly, the author falls to offer us the information about the two groups of patients and doctors thus we cannot evaluate the comparability of them. the patient may be different from each other in age, gender,physique and severity of muscle strain. these aspects can entirely be responsible for the result of the experience, and the differences between a doctor who specializes in sports medicine and a general one can lead to the same influence to the result in what dimension ,the author falls to take the condition into consideration。
secondly the augment lack the detailed information about the antibiotics thus we can make sure if the patient can afford them .Expect the antibiotics are more efficient than sugar pills the author provides no information about the medicine such as the price , bad effects, function and so forth. thus we cannot determined whether the patient can afford to using them or the feasibility to spread these kind of medicine to cure muscle strain or not. if the medicine cannot be applied to much more areas then the utilitarian of the proposal is deserve suspicions.
Thirdly, the author falls to draw the conclusion that all patients are diagnosed with muscle strain should take antibiotics as treatment instead of other methods. The function that antibiotics can affect on the patients who suffers from secondary infections and severe muscle stain is not a good indication of the possibility that the medicines could affect similarly to all patient. Apparently, the conclusion build based on the assumption that they are identify will not confidential.
Lastly, the author overlooks the other possibilities to solve these problems. May be other medicine or treatment can be easier and cheaper for patient to use and afford than the method the author refers. The author falls to dismiss them.
