家园 你是想欺负我不懂英文吗?

这个是FDA的网址: https://www.fda.gov/Drugs/ResourcesForYou/Consumers/ucm143534.htm

上面明明白白地写着

Phase 2 studies begin if Phase 1 studies don't reveal unacceptable toxicity. While the emphasis in Phase 1 is on safety, the emphasis in Phase 2 is on effectiveness. This phase aims to obtain preliminary data on whether the drug works in people who have a certain disease or condition. For controlled trials, patients receiving the drug are compared with similar patients receiving a different treatment--usually an inactive substance (placebo), or a different drug. Safety continues to be evaluated, and short-term side effects are studied. Typically, the number of subjects in Phase 2 studies ranges from a few dozen to about 300.

就懒得翻译了,要点是:有病人吃安慰剂,很明显是双盲吧?二期最大地问题是样本小,所以证据不明显,才需要三期。

唉,中医粉下次举例,能否扎实一点?

FDA的例子虽然有破绽,我也算了,我之前没想到有个道德的局限,理论上讲,是有可能有的药不道德,但有效。

另一个问题呢,能举个例子吗?

除了统计与双盲,还有没有其他更严格,更可靠的办法来验药?
