What is new?
Key finding: A framework was developed to explicitly identify and characterize research gaps from systematic reviews. Research gaps prevent systematic reviewers from making conclusions and, ultimately, limit our ability to make informed health care decisions. This framework characterizes where the evidence falls short and how or why the evidence falls short. Use of the framework promotes an explicit and systematic method of identification and presentation of research gaps from systematic reviews.
