PRECIS, which stands for "PRagmatic Explanatory Continuum Indicator Summary," is a tool designed to help researchers assess and describe the degree of pragmatism or explanatory nature in clinical trials. Developed to enhance the understanding of how different studies can impact the applicability of their findings to real-world settings, PRECIS provides a framework to evaluate various attributes of trial design that influence their external validity — that is, how well the results of the study can be generalized to routine clinical practice.
