+ | **探索性研究**:和所有临床试验一样应有清晰和明确的目的,但与确证性试验相比,它们的目的并不总是对预先定义的假设进行简单检验。此外,探索性试验可能有时需要采用更灵活的方法进行设计,以便根据积累的结果更改设计。它们的分析可能仅限于数据探索,也可能进行假设检验,但假设的拟定可能依赖于数据。尽管这类试验可能对整体的相关证据有贡献,但不能作为证明有效性的正式依据。(([[法规: | ||
+ | Like all clinical trials, an **exploratory study** should has clear and precise objectives. However, in contrast to confirmatory trials, their objectives may not always lead to simple tests of pre-defined hypotheses. In addition, exploratory trials may sometimes require a more flexible approach to design so that changes can be made in response to accumulating results. Their analysis may entail data exploration; | ||
