查找临床试验

大多数临床试验从始至终都按计划进行。但有时审判会提早终止。例如，如果参与者遇到意想不到的严重副作用，或者有明显证据表明危害大于收益，则IRB和DSMB可能会停止试验。

In some cases, a trial might be stopped because:

It is going very well. If there is clear evidence early-on that a new treatment or intervention is effective, then the trial may be halted so that the new treatment can be made widely available as soon as possible.

The results of other trials are published that answer the research question or make it irrelevant
