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
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.
