Literature review and gap mapping

A rigorous literature review defines a question, uses reproducible searches and distinguishes established evidence from uncertainty before a new study is proposed.

Original schematic relationship map for this topic; relationships are organized for study, not intended as an anatomical depiction or a diagnostic algorithm.

Concept 01

Scope

Choose concepts, population and study types relevant to the intended objective rather than searching indiscriminately.

Concept 02

Search and screen

Document databases, search strings, dates, inclusion criteria and screening decisions so others can inspect the evidence base.

Concept 03

Appraise quality

Evaluate methods, precision, populations and conflicts of interest rather than counting studies or relying on one striking abstract.

Concept 04

Map the gap

Identify unresolved mechanisms, underrepresented populations, conflicting findings or methodological limitations that a new study can feasibly address.

Education / safety note: A literature gap is not proof that a new intervention is safe or effective; ethical study design is still required.
