On the 12th and 13th of April, we had our second meeting in Barcelona with our consortium partners FAD, EPF, IR-HSCSP, Nivel, UOI and OptiMedis AG. We developed and advanced the design of the data extraction form for the analysis of randomised clinical trials. The involvement of all concerned partners is important to assure that all relevant variables are included in the extraction form. The extraction form is the key instrument to achieve comparison of self-management interventions. Questions like `How to collect information on complex self-management interventions, outcomes and target populations´ were discussed. Three organisations will review more than 4,000 articles, therefore, consistency is crucial.
