TOPIC: ARGUMENT166 - The following appeared in a local newspaper.
"People should not be misled by the advertising competition between Coldex and Cold-Away, both popular over-the-counter cold medications that anyone can purchase without a doctor's prescription. Each brand is accusing the other of causing some well-known, unwanted side effect: Coldex is known to contribute to existing high blood pressure and Cold-Away is known to cause drowsiness. But the choice should be clear for most health-conscious people: Cold-Away has been on the market for much longer and is used by more hospitals than is Coldex. Clearly, Cold-Away is more effective."

(1)作者缺乏具体的临床统计数据来评估CA和CO的效果。仅仅根据上市时间和是否被很多医院采用是没有说服力的。可能CA的价格更加便宜,或者有更好的营销策略,或者就是因为上市时间长本身,导致很多医院采用CA。并不代表CA的疗效更加好。
Perhaps the CA's scope of indications and functions is broader than the CO's which includes more diseases and symptoms.
