Finding Types of Research

What is a Systematic Review?

"A systematic review is a form of secondary research, guided by a detailed review protocol, that gathers primary studies and information from other sources on a clinical or policy question of interest and analyzes the data from these multiple studies to reach a conclusion. A systematic review involves the identification, selection, appraisal, and synthesis of the best available evidence for clinical decision making. A properly conducted systematic review uses transparent and reproducible strategies to reduce bias and instill rigor. It synthesizes information from both published and unpublished sources" (Holly, 2017).

In short, a systematic review is a structured study of studies in which only certain material that fits the predetermined inclusion criteria are analyzed. Systematic reviews and meta-analyses are often done in tandem and reported in one study.
