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 result of a study is used to prove the effect of antibiotics on the patients of muscle injures. But several predictions are unclear and the researches do not control the study very well.

First of all, we don't know whether the muscle patients will be easily suffered by secondary infections. Even if doctors suspect the secondary infection may affect patients’ healing in a short time, but we cannot assume that it occurs on all the patients. If only few patients disturbed in the experiences, it is unwise to ask all the patients taking antibiotics medicines which may also not good for human body.

Second, to give a valuable advice a study need to be scientifically controlled. How could we believe the result of such a study lacking the information both on testers and samples? We need to know the injuring level and healing situation of the patients and we also need to know whether the doctors in two groups give the same medical care to patients or not.

Do the patients at the same healing situation before them taking part in the antibiotics test? Older patients surely need to spend more time on recuperation than younger. Because in the body of older patients, the self protecting system turns weaker even cannot be felt from facet. If the patients in the second group are older than the first group it is surely that they eat less food and the molecular in muscles changes slower. The same phenomenon is also occurring on different sexes and between adults and children.

Furthermore, Dr. Alton may have more knowledge and experiences on how to take care of muscle patients than normal doctors. For example, if a doctor encourage a leg muscle patient trying to walk before completely cure, there may be occurring another accident and very dangerous to the patient. With different treating, patients' recuperations in two groups are undoubtfully different no matter they all take antibiotics or not.

Therefore, we only believe the certain and scientific researches on the efficiency of the antibiotics, the arguer need to give out more evidences to prove it.
