A16. The following appeared in an article from a health magazine.

“In a yearlong clinical trial of Mi-Quell, a new medicine for treating migraine headaches, researchers observed no significant side effects during the first five months. After six months, however, 20 percent of the subjects in the clinical trial began to report dizziness. Furthermore, during the final six months of the clinical trial, 43 of the subjects fell at least once and 18 were involved in automobile accidents. Such data indicate that Mi-Quell should be used to treat migraine headaches for up to six months, but after that time period doctors should prescribe another medicine.”

偶想到两个：

1、引致头晕、摔倒还有车祸的原因是不确定的，可能有其他的原因，比如其他疾病，insufficient

2、是否采用这种药物，应该综合考虑药效和副作用，如果药效不大副作用很高的话，也许应该放弃使用。

还有其他的么？
