PaT Plot

In randomised controlled trials, interventions may have several components, for example interviews, leaflets, group educational sessions, information packs, etc..

This simple program will enable you to depict any randomised trial graphically however many components the interventions have. It will standardise the construction process and ensure every step is covered. The PaT Plot tool is based on an original article published in the BMJ.

Once created, a PaT Plot is easy to interpret and allows clear comparisons between different arms of a trial.
