The article presents an analysis of the use of the pragmatic-explanatory continuum indicator summary (PRECIS) in helping trial designers. The authors discuss the difference between pragmatic and explanatory trials on which pragmatic help users to select between the options for care while explanatory test the casual research hypotheses. The PRECIS tool is a primary attempt to determine and quantify trial characteristics which will differentiate between the two trials which will assist the researchers in designing the scheme.
