Argument57【0806G-永不言弃小组】第8次作业 by worldbaby

The following appeared in a newsletter on nutrition and health."Although the multimineral Zorba pill was designed as a simple dietary supplement, a study of first-time ulcer patients who took Zorba suggests that Zorba actually helps prevent ulcers. The study showed that only 25 percent of those ulcer patients who took Zorba under a doctor's direction developed new ulcers, compared to a 75 percent recurrence rate among ulcer patients who did not take Zorba. Clearly, then, Zorba will be highly effective in preventing recurrent ulcers and if health experts inform the general public of this fact, many first-time ulcers can be prevented as well."
Before informing the general public the result of the study that many first-ulcers can be prevented by take multimineral Zorba in certain amount, the argument should be examined from several other angles. The researchers of the study have already assumed that the Zorba can effectively keep the ulcers from recurring without examining other possible factors which may lead to the same result.
First of all, the study which leads to the results is doubtful. For an experiment to be effective, it should make a balance between the experimental and the control group. While in the study above, we have nothing about the ages, the backgrounds and the general health state of the patients. And even we do not know nothing that whether the ulcer patients who took Zorba are the same ages, backgrounds and healthy level as those who did not take Zorba. Perhaps that those Zorba-takers are people who ate healthily, exercised regularly and never smoke, whose lifestyle can effectively avoid the ulcer recurrence. Perhaps the latter ones who have 75 percent recurrence rate are heavy smokers, and grossly lacking of good dormancy, whose lifestyle are tend to suffer from the recurrence of ulcers. The cases are true of the age. Younger people are less likely to face the ulcers. In addition, the arguers are fail to do a persuasive study which make the result unconvincing.
Secondly, it is unfair that the author assumes that the Zorba is the only onw that is highly effective in preventing recurrent ulcers. There is no evidence to support that. Lacking such evidence, it is also equally that aside from taking Zorba, other medicine will play the same role in preventing the ulcers. For instance, vitamin B2 is of essential use for fighting with the ulcers. Besides, as a common sense, it is well-known that vegetables or fruits juice which is full of plenty of vitamin and mineral elements is also effective in preventing the ulcers. Without ruling out such alternative ways of preventing ulcers in the experiments, it is hasty to draw the generalization that many first-time ulcers of the public can be prevented as well.
Finally, even if assuming the result of the study is correct, other problems need to be considered: can many first ulcers be prevented as well? Whether the Zorba have adversely effect on the commons? The fact is that the study only shows us that Zorba will be highly effective in preventing recurrent ulcers, which might not be same to the first-time illness. If it supposed that the absence of recurrence is due to the antibody of ulcers, there is no evidence to indicate the fist-time ulcers can be prevented. It is similar to the side-effect, is there anything in the Zorba may have adversely effects on the patients, such as affecting the women's ability to bear healthy children or inducing high blood pressure for certain people. Consequently, the arguer failed to rule out such possibilities which make the conclusion inadvisable for some people.
In a word, for a study to be effective, it must be strictly controlled and have a broad cross- sectional people involved. Besides, other alternative solutions should be included. |
