The Stages of Trials
This chapter discusses the stages of a clinical trial. The stage of a trial is different from phase of a trial. The stage is a period within the course of a trial. The phase is a facet of activities in a sequence of activities related to developing and testing a treatment for possible use in human beings. The sojourn times by stage vary depending on the trial. They can be days, weeks, months, or years; months or years in the case of long-term trials. Stages can be seen as two-dimensional arrays with the following activities, overlaid on stages, since they run across stages: training and certification, data collection and processing, monitoring, data analysis, and paper writing.
