Main Findings
Over half of the trials (58%) in the specialised register published
from 2010 -2011 were not being disseminated in Cochrane SRs and as such
could be considered wasted evidence. Of the unused trials 45% of these
could be used if an existing review was updated. Cochrane review authors
are encouraged to update their review every two years(16) and it is surprising to find a large number of
trials of this age that have not been incorporated into CGF SRs. In this
project we have identified the reviews that each of these trials could
fit and they will be prioritised and updated accordingly.
