Superfilters Website: A Literature Searching Tool for Clinicians and Review Authors

Nancy L Wilczynski, N Hobson, C Cotoi, R Brian Haynes

“To develop a superfilters website that

provides clinicians and review authors with the

opportunity to search across several electronic

databases simultaneously with empirically derived,

high performance, search filters.”



Superfilters Website: A Literature Searching Tool for Clinicians and Review Authors

Nancy L Wilczynski, N Hobson, C Cotoi, R Brian Haynes

“To add ‘capture-mark-recapture’ (CMR) statistical

modeling to the review authors’ superfilter site to

help those searching for all available evidence to

determine whether to continue or stop searching,

for example, when conducting systematic reviews”
