Systematic reviews have a median completion time of 18 months.This will help guide you and your team through the process.īefore starting a systematic review, consider the following: You should also begin by printing out the PRISMA checklist. We will discuss many of the PRISMA guidelines throughout this guide. The first one we will start with here is PRISMA or Preferred Reporting Items for Systematic Reviews and Meta-Analyses. PRISMA provides a statement for their guidelines. There are a number of organizations that can help you through the process of choosing your topic, registering your review, and writing your review. Quality systematic reviews follow a strict set of criteria for creation. The systematic review contains the narrative portion and the meta-analysis contains the data and graphs portion. Systematic Reviews and if included meta-analysis are in depth reviews of a specific clinical question. Defining the Role of Authors and Contributors.

Understanding why evidence from randomised clinical trials may not be retrieved from Medline: comparison of indexed and non-indexed records. Making literature searches easier: a rapid and sensitive search filter for retrieving randomized controlled trials from PubMed. A simplified search strategy for identifying randomised controlled trials for systematic reviews of health care interventions: a comparison with more exhaustive strategies.

Retrieving randomized controlled trials from medline: a comparison of 38 published search filters. McKibbon KA, Wilczynski NL, Haynes RB Hedges Team. It's been observed that many RCTs are now missed by the RCT publication type. However, the Cochrane Collaboration ceased tagging MEDLINE records in 2006. Used as limits or their underlying controlled vocabulary terms, they've been reported to produce extremely high precision (94%!) with only a small sacrifice in sensitivity. It is:įor precise limiting when you're pressed for time, you can use the randomized controlled trial limits in either PubMed or Embase. 'randomized controlled trial'/exp OR 'controlled clinical trial'/exp OR randomized:ti,ab OR placebo:ti,ab OR 'drug therapy':lnk OR randomly:ti,ab OR trial:ti,ab OR groups:ti,abĪs an alternative, Royle and Waugh published 'simplified' strategy that is nearly as effective as the foregoing methods (Sensitivity, 97% precision, 29% ), induces little or no bias, and is easy to transfer to interfaces other than PubMed. "randomized controlled trial" OR "controlled clinical trial" OR randomized OR placebo OR "drug therapy" OR randomly OR trial OR groups The "Highly Sensitive Search Strategy" has been used widely to retrieve randomized controlled trials and other types of evidence for systematic reviews. Section 6.4.11 of this Handbook includes strategies for limiting searches to controlled trials. The Cochrane Collaboration publishes an extensive handbook for systematic reviews. ('clinical':ti,ab AND 'trial':ti,ab) OR 'clinical trial'/exp OR random* OR 'drug therapy':lnk (clinical AND trial) OR "clinical trials as topic" OR "clinical trial" OR random* OR "random allocation" OR "therapeutic use" and provides high sensitivty (99%) at the expense of precision (10%). The NCBI's Clinical Queries for Therapy (sensitive) is based on work of Haynes, et al. One of the following filters should be adequate for most investigations. There are dozens of filters available for limiting searches to randomized controlled trials.
