Missing Data and Attrition
In June 2006 we hosted a workshop, funded by the MRC’s Population Health Sciences Research Network, entitled “Maximising Return from Cohort Studies: Prevention of attrition and efficient analysis”. A report on the workshop, along with several presentations, can be found here. In October 2009 we held a second workshop; the presentations from that workshop can be found here. We are also joint grantholders for two cross-unit appointments considering attrition in MRC-funded cohort studies, again funded by PHRSN.
