primary prevention trials

Unfortunately, primary prevention trials that start in childhood would be lengthy, expensive, and logistically nearly impossible, "said Ulrich and Potter."

不幸的是，从童年开始的早期预防试验时间冗长、花费巨大和在后勤上几乎是不可能的。Ulrich和Potter如是说。

"Is aspirin really that good or is there some other explanation for the findings that differ so much from those of the WHS and other primary prevention trials?" he asked.

他问到：阿斯匹林真的这么好还是有其它的原因，使这次的发现与世界健康调查和其它的一期预防实验的结果差距这么大？

Although several large trials of aspirin for primary prevention have included diabetic subgroups, no trial has been specifically dedicated to looking at the effects of aspirin in this patient group.

尽管数个关于阿司匹林的大型实验作为初级预防包括了糖尿病亚组，但是没有实验特别针对阿司匹林对糖尿病的效果来研究。
