In this procedure, events which cause anxiety are recalled in imagination, and then a relaxation technique is used to dissipate the anxiety.
A young researcher's guide to a systematic review Series: Part04 - Types of articles: A guide for young researchers Key takeaways: A systematic review is a thorough and detailed review of existing literature on a particular topic, designed to address a specific question. Systematic reviews are especially important in evidence-based medicine.
A good systematic review begins with a protocol that defines the study design, objectives, and expected outcomes; follows the PRISMA guidelines, and should be registered in a recognized protocol registry.
Apr 29, A systematic review is a highly rigorous review of existing literature that addresses a clearly formulated question. The review systematically searches, identifies, selects, appraises, and synthesizes research evidence relevant to the question using methodology that is explicit, reproducible, and leads to minimum bias.
Systematic reviews are regarded as the best source of research evidence.
Systematic reviews are absolutely crucial in the field of evidence-based medicine, but are also highly valued in other fields. A systematic review is more exhaustive than a literature review as it includes both published and unpublished literature, often called grey literature.
Grey literature is a significant part of a systematic review and adds value to the review.
This is because grey literature is often more current than published literature and is likely to have less publication bias. Grey literature includes unpublished studies, reports, dissertations, conference papers and abstracts, governmental research, and ongoing clinical trials.
Conducting a systematic review is a complex process. This article aims to guide you on the different kinds of systematic review, the standard procedures to be followed, and the best approach to conducting and writing a systematic review.
Types of systematic reviews Qualitative: In this type of systematic review, the results of relevant studies are summarized but not statistically combined. This type of systematic review uses statistical methods to combine the results of two or more studies.
A meta-analysis uses statistical methods to integrate estimates of effect from relevant studies that are independent but similar and summarize them. Writing a protocol Any good systematic review begins with a protocol. According to the National Institutes of Health NIHa protocol serves as a road-map for your review and specifies the objectives, methods, and outcomes of primary interest of the systematic review.
The purpose of having a protocol is to promote transparency of methods.A systematic review answers a defined research question by collecting and summarising all empirical evidence that fits pre-specified eligibility criteria.
A meta-analysis is the use of statistical methods to summarise the results of these studies. PROSPERO: An international database of prospectively registered systematic reviews in health and social care.
Key features from the review protocol are recorded and maintained as a permanent record. Open Science Framework: An open source web application that connects and supports the research workflow. Researchers use the OSF to collaborate, document, archive, share, and register research . An effective systematic review "collates all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question" (Cochrane Handbook for Systematic .

The massive expansion of research output, both in peer-reviewed publications, and unpublished, e.g. in conference presentations or symposia, mean it is difficult to establish what work has been done in your area already, and to ensure that clinical practice keeps up to date with the best research evidence.
