Identify different types of review articles
= Predetermined scales that guide decisions for ranking evidence; levels of evidence
Let's focus on the review articles in this page
See the Evidence Hierarchy page for other types
Level I
Meta-analysis
= A scholarly paper that combines results of studies, both published and unpublished, into a measurable format and statistically estimates the effects of proposed interventions
Forest plot
= A style of data visualization for meta-analysis results
5 tips for understanding data in meta-analyses
(1) Don’t jump to conclusions without looking carefully at the context and perspective
(2) Don’t lose sight of what data is not in the meta-analysis
(3) Remember to check if there are signs that the studies might be too different in some way
(4) See if one (or a few) results are carrying most of the weight
(5) Size isn’t everything – and be careful of “vote counting”
Systematic reviews of experiments / quasi-experiments
= A rigorous and systematic synthesis of research findings from experimental and quasi-experimental studies about a clinical problem
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)
Clinical Practice Guidelines
=Statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options
University of Washington Health Sciences Library: Care provider toolkit
Summaries
= Best practice recommendations based on an appraisal of information about a particular practice question
Example: Joanna Briggs Institute (JBI)
Synopses
= Brief descriptions of evidence that provide an overview of keypoints of evidence from multiple sources
Example 1: Database of Abstracts of Reviews of Effects (DARE)
Example 2: American College of Physicians Journal Club
Level V
Integrative review (systematic review of non-experimental)
= Scholarly papers that include published nonexperimental studies in the synthesis to answer clinical questions
Metasynthesis
= A systematic review that contains only qualitative studies; a scholarly paper that combines results from qualitative studies
Level VI
Concept analysis
= A process that explores the attributes and characteristics of a concept
Level VII
Narrative review
= Papers based on common or uncommon elements of works without concern for research methods, designs, or settings
