COMET stands for the ‘Core Outcome Measures in Effectiveness Trials’ Initiative. It has developed a database of all studies relevant to the development of core outcome sets for use in clinical trials. The COMET initiative was set up to help in two main ways:
*to provide the COMET database as a central point where researchers, practitioners and patients can find core outcome sets that have already been developed or are still under development.
* Provide materials to support the teams who are working on core outcome sets
