what is systematic literature reviews

A systematic review collects secondary data, and is a synthesis of all available, relevant evidence which brings together all existing primary studies for review (Cochrane 2016). A systematic review differs from other types of literature review in several major ways.

The best reviews synthesize studies to draw broad theoretical conclusions about what a literature means, linking theory to evidence and evidence to theory. This guide describes how to plan, conduct, organize, and present a systematic review of quantitative (meta-analysis) or qualitative (narrative review, meta-synthesis) information.

A Systematic Literature Review (SLR) is a research methodology to collect, identify, and critically analyze the available research studies (e.g., articles, conference proceedings, books, dissertations) through a systematic procedure [12]. An SLR updates the reader with current literature about a subject [6].

Systematic reviews are a type of literature review of research that require equivalent standards of rigour to primary research. They have a clear, logical rationale that is reported to the reader of the review. They are used in research and policymaking to inform evidence-based decisions and practice. They differ from traditional literature ...

A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [ 1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature ), then analyzes, describes, critically appraises and ...

Screen the literature. Assess the quality of the studies. Extract the data. Analyze the results. Interpret and present the results. 1. Decide on your team. When carrying out a systematic literature review, you should employ multiple reviewers in order to minimize bias and strengthen analysis.

What is a systematic review? A Systematic Review (SR) is a synthesis of evidence that is identified and critically appraised to understand a specific topic. SRs are more comprehensive than a Literature Review, which most academics will be familiar with, as they follow a methodical process to identify and analyse existing literature (Cochrane ...

Systematic review vs literature review. A literature review is a type of review that uses a less systematic and formal approach than a systematic review. Typically, an expert in a topic will qualitatively summarise and evaluate previous work, without using a formal, explicit method.

A systematic review is a summary of the medical literature that uses explicit and reproducible methods to systematically search, critically appraise, and synthesize on a specific issue. It synthesizes the results of multiple primary studies related to each other by using strategies that reduce biases and random errors.[ 7 ]

Introduction and background. A literature review provides an important insight into a particular scholarly topic. It compiles published research on a topic, surveys different sources of research, and critically examines these sources [].A literature review may be argumentative, integrative, historical, methodological, systematic, or theoretical, and these approaches may be adopted depending ...

A systematic review is a literature review that gathers all of the available evidence matching pre-specified eligibility criteria to answer a specific research question. It uses explicit, systematic methods, documented in a protocol, to minimize bias, provide reliable findings, and inform decision-making. ¹

Several CDC librarians have special training in conducting literature searches for systematic reviews.

Thacker CDC Library by email [email protected] or telephone 404-639-1717.

Literature reviews establish the foundation of academic inquires. However, in the planning field, we lack rigorous systematic reviews. In this article, through a systematic search on the methodology of literature review, we categorize a typology of literature reviews, discuss steps in conducting a systematic literature review, and provide suggestions on how to enhance rigor in literature ...

A systematic review is an evidence synthesis that uses explicit, reproducible methods to perform a comprehensive literature search and critical appraisal of individual studies and that uses appropriate statistical techniques to combine these valid studies.

This article provides a step-by-step approach to conducting and reporting systematic literature reviews (SLRs) in the domain of healthcare design and discusses some of the key quality issues associated with SLRs. SLR, as the name implies, is a systematic way of collecting, critically evaluating, integrating, and presenting findings from across ...

Systematic reviews, meta-analyses, scoping reviews, rapid reviews, narrative syntheses, practice guidelines, among others, are all forms of knowledge syntheses. For more information on types of reviews, visit the "Types of Reviews" tab on the left. A systematic review varies from an ordinary literature review in that it uses a comprehensive ...

Systematic reviews are characterized by a methodical and replicable methodology and presentation. They involve a comprehensive search to locate all relevant published and unpublished work on a subject; a systematic integration of search results; and a critique of the extent, nature, and quality of evidence in relation to a particular research question. The best reviews synthesize studies to ...

Rapid review. Assessment of what is already known about a policy or practice issue, by using systematic review methods to search and critically appraise existing research. Completeness of searching determined by time constraints. Time-limited formal quality assessment. Typically narrative and tabular.

Systematic literature review. What is it and when should we use it? Systematic reviews have foremost been developed within medical science as a way to synthesize research findings in a systematic, transparent, and reproducible way and have been referred to as the gold standard among reviews (Davis et al., 2014).

Systematic Literature Reviews; What is a Literature Review? What is a Literature Review? A literature review is an academic text that surveys, synthesizes, and critically evaluates the existing literature on a specific topic. It is typically required for theses, dissertations, or long reports and serves several key purposes:

When interpreting results and drawing conclusions, authors of systematic reviews should consider the limitations of the evidence included in their review. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach provides a framework for the explicit consideration of the limitations of the evidence included in a ...

A systematic review collects all possible studies related to a given topic and design, and reviews and analyzes their results [ 1 ]. During the systematic review process, the quality of studies is evaluated, and a statistical meta-analysis of the study results is conducted on the basis of their quality. A meta-analysis is a valid, objective ...

Speaker 1: The first step of doing a systematic literature review is coming up with a review question, like what do you actually want to know about the world and how can you phrase that as a simple question. You can write down all of the questions you want and then choose from the best one or a combination but I like to go to ChatGPT and use them as like a sounding board and a research ...

Systematic reviews and other types of literature reviews are more prevalent in clinical medicine than in other fields. The recurring need for improvement and updates in these disciplines has led to the Living Systematic Review (LSR) concept to enhance the effectiveness of scientific synthesis efforts. While LSR was introduced in 2014, its adoption outside clinical medicine has been limited ...
