Abstract This systematic review explored associations between smoking and health outcomes involving the musculoskeletal system.
Characteristics[ edit ] A systematic review aims to provide a complete, exhaustive summary of current literature relevant to a research question. The first step in conducting a systematic review is to create a structured question to guide the review.
The Methodology section of a systematic review will list all of the databases and citation indexes that were searched such as Web of ScienceEmbaseand PubMed and any individual journals that were searched.
The titles and abstracts of identified articles are checked against pre-determined criteria for eligibility and relevance to form an inclusion set. This set will relate back to the research problem.
Each included study may be assigned an objective assessment of methodological quality preferably by using methods conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA statement the current guideline  or the high quality standards of Cochrane.
An additional rater may be consulted to resolve any scoring differences between raters. Groups like the Campbell Collaboration are promoting the use of systematic reviews in policy-making beyond just healthcare.
A systematic review uses an objective and transparent approach for research synthesis, with the aim of minimizing bias. While many systematic reviews are based on an explicit quantitative meta-analysis of available data, there are also qualitative reviews which adhere to standards for gathering, analyzing and reporting evidence.

Defining a question and agreeing an objective method. For example, only selecting research that is good quality and answers the defined question. This can include how the research was done often called the method or 'intervention'who participated in the research including how many peoplehow it was paid for for example funding sources and what happened the outcomes.
This combination of data can be visualised using a blobbogram also called a forest plot. Because this combined result uses data from more sources than just one data set, it's considered more reliable and better evidence, as the more data there is, the more confident we can be of conclusions.
Research fields[ edit ] Medicine and biology[ edit ] The Cochrane is a group of over 37, specialists in healthcare who systematically review randomised trials of the effects of prevention, treatments and rehabilitation as well as health systems interventions.
When appropriate, they also include the results of other types of research. Diagnostic test accuracy reviews assess how well a diagnostic test performs in diagnosing and detecting a particular disease. Methodology reviews address issues relevant to how systematic reviews and clinical trials are conducted and reported.
Qualitative reviews synthesize qualitative and quantitative evidence to address questions on aspects other than effectiveness. Overviews of Systematic Reviews OoRs are a new type of study in order to compile multiple evidence from systematic reviews into a single document that is accessible and useful to serve as a friendly front end for the Cochrane Collaboration with regard to healthcare decision-making.
The Cochrane Collaboration provides a handbook for systematic reviewers of interventions which "provides guidance to authors for the preparation of Cochrane Intervention reviews.
The Campbell Collaboration "helps people make well-informed decisions by preparing, maintaining and disseminating systematic reviews in education, crime and justice, social welfare and international development.
The Campbell Collaboration was created in and the inaugural meeting in Philadelphia, USA, attracted 85 participants from 13 countries. Early attempts to transfer the procedures from medicine to business research have been made by Tranfield et al.
Based on the experiences they have made in their own discipline, these authors have adapted the methodological steps and developed a standard procedure for conducting systematic literature reviews in business and economics. They proposed several solutions, including limiting studies in meta-analyses and reviews to registered clinical trials, requiring that original data be made available for statistical checking, paying greater attention to sample size estimates, and eliminating dependence on only published data.
Some of these difficulties were noted early on as described by Altman:When writing about treatment efficacy, A systematic review uses a reproducible methodology to select primary The BMJ (British Medical Journal), and the Canadian Medical Association Journal.
Core basic science and biology journals include Nature, Science and Cell. Predatory journals. Journal of Epidemiology and Community Health is a leading international journal devoted to publication of original research and reviews covering applied, methodological and theoretical issues with emphasis on studies using multidisciplinary or integrative approaches.
Rule 3: Take Notes While Reading. If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper.

You are here writing of the manuscript and the meta-analysis. BD was involved in. Mar 06, · Review articles are divided into 2 categories as narrative, and systematic reviews. Narrative reviews are written in an easily readable format, and allow consideration of the subject matter within a large spectrum.
However in a systematic review, a very detailed, and comprehensive literature surveying is performed on the selected topic.
