treatment group

基本解釋

They were randomly assigned to either a treatment group or a placebo group.
他們被隨機安排到治療組和安慰劑組。
For example, it's impossible to implement such a radical diet without kids and their parents realizing they're in the treatment group.
比如，如果小孩和家長沒有意識到這是一種治療手段，這樣全新的食療就不可能産生傚果。
The group on placebo pills showed improvements both at the half way point and at the end of the period, when compared with the no-treatment group.
相對於不做任何処理的那組，服用安慰劑的病人在第二周開始和結(jié)束時病情都有所好轉(zhuǎn)。
