PRECIS-2

Designing clinical trials is challenging. PRECIS – PRagmatic Explanatory Continuum Indicator Summary – is a clever acronym for a tool to help trialists designing clinical trials consider where they would like their trial to be on the pragmatic/explanatory continuum.

The PRECIS-2 website has two functions

  1. a training resource;
  2. a database of trials that have been scored using PRECIS-2

Trialists working on their own trial can apply for a password so that their team can score their trial while developing the trial design and protocol.
This trial design information will only be visible to trialists using a password until they decide to make this information publically available. We advise one password per trial team so you all have access to score the same trial. A PRECIS-2 wheel will be generated, based on all the scores, and can be used for discussion and consensus.

The database of trials contains trials that are a spectrum of pragmatic trials. We hope this will be helpful to researchers who can then search for trials on particular topics and consider the trial design. In addition trialists can look at the internal validity using the Risk of Bias tool©.
