Dental school faculty members, as well as many practitioners, are interested in evaluating products and procedures used in clinical practice. Research design and statistical analysis, however, can pose problems to some, while others would like to avoid detailed consideration of protocol until after a preliminary investigation. Sequential trials methods provide an analytical structure that is both easy to use and statistically valid.
牙科学院的教员以及许多从业者都对评估临床实践中使用的产品和程序感兴趣。然而，研究设计和统计分析可能会给一些人带来问题，而另一些人则希望在进行初步调查之后再详细考虑方案。序贯试验方法提供了一种既易于使用又具有统计有效性的分析结构。
