Start simple with real ideas that are meaningful to your clinical practice and specialty. Refine your ideas into a more defined research question. This research question needs to be relevant, needs to translate to the

For this reason, it needs to be well defined in advance and needs to be easily measurable with tools that are ideally readily available, simple to use, accurate, and validated. The closer an

This chapter discusses the various types of trials defined by regulatory agencies that are required to move a drug, vaccine, biologic or devices that carry significant risk from preclinical testing to marketing approval. This chapter focuses specifically on early phase trials

The advent of the RCT is relatively recent, with the first major trial reporting results shortly after World War II. However, the various design elements that provide the rigor of the RCT had developed over hundreds of years. In fact, the basic idea of lea

A key issue in the design and interpretation of results for a factorial design is that of effect modification, or treatment interaction. When interaction exists betwe

The first being increased precision which allows a reduction in the required sample size, often dramatic, compared with a parallel-group trial. The second advantage is that it may enhance recruitment as each study participant will receive an active treatment i

Since patients within a provider, clinic, or hospital are more likely to be similar than patients from another provider, clinic, or hospital, this correlation, called the intraclass correlation (ICC), must be accounted for in t
