Question

Study design
Thirty healthy subjects (14 men and 16 women) between 20
and 39 y of age were recruited. Subjects were asked to abstain
from consuming tea, tea-related products, vitamins, minerals,
and dietary or herbal supplements throughout the study period.
Heavy tea drinkers and users of hormone therapy or antibiotics
were excluded. All subjects were screened with a complete medical
history and signed the informed consent form.Arandomized
33 crossover design with a 1-wk washout period was used for
the intervention study. The subjects were randomly assigned to 3
different sequences of GT, BT, or GTS at the University of
California, Los Angeles (UCLA), General Clinical Research
Center (GCRC).

30 個健康的主題(14個男人和16名婦女) 在20之間
並且年齡的39 y被招募。 主題被要求棄權
從吃完茶，有關茶的產品，維生素，礦物質中，
以及在整個研究時期期間的飲食或者草本植物的補充。
激素治療或者抗菌素的難消化的茶飲者和用戶
被排除。 全部主題被一次完全的體格檢查篩選
歷史和在明智的應允form.Arandomized上簽字
3 _ 有一個1－wk失敗時期的3種交叉的設計被使用為
干涉研究。

Answer 1

Study design研究計劃的設計
Thirty healthy subjects (14 men and 16 women) between 20 and 39 y of age were recruited.
徵召了身體健康, 年齡介於20至39歲的男性14人﹑女性16人, 總共30位接受實驗。

Subjects were asked to abstain from consuming tea, tea-related products, vitamins, minerals, and dietary or herbal supplements throughout the study period.
在整個實驗期間他們的茶﹐茶製品﹑維他命﹑礦物質﹑正規飲食與草本補品的的攝取都受到管制。

Heavy tea drinkers and users of hormone therapy or antibiotics were excluded. All subjects were screened with a complete medical history and signed the informed consent form.
參加實驗者都經過完全的病歷調查後再簽署同意通知書﹐因此茶癮很重的人﹑正在接受賀爾蒙治療或抗生素的人都被排除在外。

A randomized 3x3 crossover design with a 1-wk washout period was used for the intervention study. The subjects were randomly assigned to 3 different sequences of GT, BT, or GTS at the University of California, Los Angeles (UCLA), General Clinical Research Center (GCRC).
在加州洛杉磯大學一般臨床研究中心﹐參加實驗者被安排以隨機的順序取用綠茶﹑紅茶或綠茶萃取物。為了符合介入研究的精神﹐採用了3對3隨機組合的設計並給予接受實驗者一個禮拜的時間讓體內殘存會妨礙實驗正確性的物質排除乾淨。
