This study is an adaptive, randomized, double-blind, placebo-controlled trial to evaluate the safety and efficacy of novel therapeutic agents in hospitalized adults diagnosed with COVID-19.
什么是double-blind
In many trials, no one—not even the research team—knows who gets the treatment, the placebo, or another intervention. When participants, family members, and staff all are “blind” to the treatment while the study is underway, the study is called a “double-blind, placebo-controlled” clinical trial.
那位讲母亲经历的帖，说好听的是在编故事，说难听的就是胡说八道。我把我写的再发一遍：
关于对这个trial是如何操作的，下面是summary的第一句

中华民族就是缺乏较真的精神，大到：才让ccp掌控自己的命运，但凡有打破砂锅问到底的精神，ccp也不会横行霸道。小到：假冒伪劣商品泛滥。
就是这种凡事和稀泥的人生态度，毁了自己败了民族害了世界。
逛坛子也只找和家人有关的。太不关心自己了
磨难, 被别人山塞, 诟病。我们等着它的Clinical trial 结果等了两个多月, 从中国二月份开始，经历中国trial fail，who 帮着造谣，到我们终于取得了一个阶段性的significant 实验结果. 美国这个Clinical trial 的成功也代表了美国科技, 研究的严谨, 认真. 绝对不是象某国那样随便违反制度, 规则的
而妈妈不信中药没吃进了ICU，好不容易进个西药trial，万恶的美帝还把妈妈分进placebo组，连片西药的影子都看不见！生死关头妈妈终于吃了补中益气丸，痊愈出院了！补中益气丸，武肺神药！今天你吃了吗？拉个近景来个特写，这个怎么拍要问问3721，她是行家.....因为半路杀出个认真的网友口木呆，这广告没能拍完，只能脑补一下了，但谁会遗憾？
我这个八杆子打不着的闲杂人等看得痛心疾首。
当然，修图调色还是干的。
骗子撒个谎，总是顾头不顾腚的，露丑的地方太多了。
在美国trial的进行过程是很严格的，根本不可能出现那样的错误的。
非常反感蹭热点话题添油加醋编故事搏同情/带节奏/夹私货的。
