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."
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实验两组执行的医生不同，由于两个医生技术水平及专业的不同，对两组的预后及疗效就不同
2实验两组的具体情况不清楚，如果两组没有在相同条件下，那得出的结果就没有可信度
3两组的治疗方案交代不清楚，是否有其他治疗同时进行。



  The result of the study based on the two incomparable groups that all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment is failed the support the hypothesis that secondary infections may keep some patients from healing quickly after severe muscle strain. A careful examination of the argument in the following will reveal how unwarranted the study is.
   First of all, the conductors in the two groups are not the same. The two different doctors who treated the two different groups may influence the result. The first doctor is specialized in sports medicine, while the second is a general physician. The skills of the two doctors may determine the prognosis of the patients.  That's to say, the first doctor who is specialized in ports medicine may be more able to treat the muscle strain. So the recuperation time of the first group is 40 percent quicker may be result from the techniques of the doctors, not the antibiotics .
Second, the situations of two groups in the study are uncertain. Whether the two groups have the equal amount patients?  Whether the degrees of their injuries are similar? Whether the circumstances where they are having their treatments are the same?  May the first group is less serious than the second. All of the things above are not clear. Without excluding a lot of other factors that may influence the results, we can’t agree with the arguer.
  Third, the argument lacks of the details of the treatments. Other therapies may be existed as well as the antibiotics. In the first group which Dr Newland took antibiotics regularly throughout their treatment may be undertaken other therapies like rehabilitations trainings, physical therapies or take other medicines at the same time. Also, in the second group treated by Dr. Alton may be given sugar pills without any other therapies. If so, the effects of the two groups will definitely different. As a result, more descriptions and explanations of the treatments of the two groups should be demonstrated.
  In a word, the result of the study based on two incomparable groups is insignificant and is unable to support the hypothesis. Advanced researches and studies are needed.
