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."

Before the arguer made a suggestion that all muscle strain patients should take antibiotics as part of their treatment, he provides a study of two groups of patients and concludes that secondary infections keep some patients from healing quickly after severe muscle strain. However, the scenario suffers from several flaws which make the contention unconvincing.
Firstly, the two groups of patients in the study might not be scientifically chosen and classified which could result in other factors be neglected in the seeking of true reasons that prevent patients from healing from muscle strain quickly. Perhaps, people from 1st group are those who are young and of better health conditions, or those who pay special attention to exercises and lead a healthy life style; while the 2ed group participants are not as healthy as those in 1st group. Perhaps, the average level of the muscle injury in 2ed group is higher than 1st group. In this sense, it cannot surely conclude that it is the antibiotic that takes decisive effects in the healing process.
In addition, the patients in 2ed group believed they were taking antibiotics while they actually took sugar pills which might cause the wrong psychological anticipation that would cause the carelessness in defending infections. In this sense, the chance to be infected is rising, besides the fact they were not taking real antibiotics.
Secondly, Dr. Newland and Dr. Alton who are treating respectively two groups are adopting different therapies, which might contribute to the healing of the patients. Further, Dr. Newland, who specializes in sports medicine, might be good at assisting patients to do some recovery exercise, which results in sooner recovery.
Finally, the arguer ignored that side effects might happen to different people with distinct body conditions. For instance, the patients might be allergic to some certain antibiotics which lead to severe body reactions. Or the injection of the antibiotics would cause drug reliance and weaken the innate immune system which might be a great loss to one's body shield. Before prescribing antibiotics to all patients, he should be sure of the side effects might exist to different people.
In sum, to convince me that all patients who are diagnosed with muscle stain would be advised to take antibiotics as part of their treatment, the information of two groups of people in the study should be provided, including the participants' quantity, age, physical condition, level of muscle strain, etc. Meanwhile, the treatment of Dr. Newland and Dr. Alton should be exposed to us, in order to rule out other factors that could affect the results of the study. What's more should be take into account is that the side effect would possibly happen to patients. |
