In this argument, the arguer concludes that in order to prevent secondary infections(infection作“传染”时, 只有当“传染病”时[c]), all patients with muscle strain should take antibiotics. To substantiate his conclusion, he(he/she) cites a clinical study which seemingly shows the diference(difference) in the recuperation time of muscle strain that antibiotics can make . But there are some fallacies in the line of reasoning.
In the first place, the hypothesis that secondary infections might lead to longer healing time of muscle strain, has been proved by insufficient preliminary results of a study. First, since the two groups of patients received different treatments from two doctors in two different major fields, the conclusion drawn from the results may not sound convincing for the antibiotics are not the only virable(variable) in the study. Maybe Dr. Newland , who is a specialist of sports, paid more attention to the sports function of patients and gave a prescripion(prescription) which heals muscle strain more quickly, while Dr. Alton, who is a general physician , would probably more emphasize the overall condition of the patients, such as the vital signs, the other possible clinical complications rather than the recuperation time of a certain part of the body. It's highly likely that it's the special treatment they receive other than the antibiotics that leads to the sharp decrease of recuperation time. Secondly, the arguer fails to provide adequate information of patients in the study. How many patients are invovled(involved) ? Do the two groups of patients have the same level of severity of muscle strain? What about the average age of the patients? Because based on common sense, children could heal much more quickly than elders, especially old people. Moreover, the arguer fails to rule out the possibility that some of the patiens(patients) receive other treatment, such as antihypertensive drugs, hypoglycemic drugs, or immunosuppressor, which might elongate or shorten the rcuperation(recuperation) time. To fully validate the conclusion, the arguer must provide evidence to prove that the treatment that the patients receive and the conditon(condition) of patients are the same, including the same level of severity of muscle strain, the approximate average age. And also ,the possibility that some of the patients received other treatment during the study should be ruled out.

In the second place, even if antibiotics do can significantly reduce the recuperation time, it is a little too hasty to conclude that all patients with muscle strain necessarily need to take antibiotics. First of all, some of the patients might not suffer from secondary infection. Then, there are some patients who might be allergic to certain kind of antibiotics. And also, regular using of antibiotic might lead to the resistence of bacterium to the antibiotics, which might cause hard control of secondary infection. Finally, for special group of patients, for instance pregnant women, the antibiotics are highly forbiddened, for the antibiotics might contribute to the gene mutation of a baby ,or some congenital deficiency, even abortion of a baby.
In sum, this argument is not well reasoned. To make this conclusion sound more convincing, more details, explanation about the study should be provided to ensure only one variable in the study, namely antibiotics. Furthermore, it would be more cogent if evidence has been given to prove that antibiotics are one hundred percent safe for all people.
