In describing the purpose of their study, authors will present a mini literature review to discuss how previous research has led up to their original research project.
Review articles summarize or synthesize content from earlier published research and are useful for surveying the literature on a specific research area. Review articles can lead you to original research articles.
Narrative Review: a literature review that describes and discusses the state of the science of a specific topic or theme.
Systematic Review: a comprehensive review of all relevant studies on a particular topic/question. The systematic review is created by following an explicit methodology for identifying/selecting the studies to include and evaluating their results.
Meta-Analysis: the statistical procedure for combining data from multiple studies. This is usually, but not always, presented with a systematic review.
