title: GRAPPA Responder Index Project (GRACE): a report from the GRAPPA 2011 annual meeting.
abstract: The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) established the GRAPPA Composite Exercise (GRACE) to compare existing and emerging composite disease activity and responder measures. At the GRAPPA 2010 annual meeting, initial results from this project were presented, and voting on available measures took place. At the GRAPPA 2011 meeting, further comparisons of new and existing measures were made, along with an outline plan for further work.
