Systematic Reviews

This class will provide an overview of the data collection process for your review – whether scoping or systematic. The importance of data cleaning for consistency to ensure accurate identification of comparable outcome measures across studies and how to do so will be discussed. We will review the process and tools to use, discuss recommended practices, and share lessons learned. Participants will receive resources and information on recommended practices for performing this important step in your review.

This class will provide a comprehensive look into critical steps of the review process – establishing your inclusion and exclusion criteria and then using those criteria to conduct the screening steps to select relevant studies for your review. Participants will receive resources and information on best practices for performing these steps to facilitate an effective and rigorous review.

This class is a part of the systematic reviews class series. Systematic and scoping reviews are a complex undertaking and involve multiple steps in order to produce a quality review. Developing a protocol to guide the conduct of your review is a critical step. This class explains what a review protocol is, how to develop one, and how to use it for the conduct of your review. Resources to develop the protocol and where to register or publish it will be shared.

This session focuses on defining the scope of your review by applying techniques to formulate a workable research question. The class introduces various frameworks used for developing a research question, and presents the requirements and steps involved in conducting the literature search for the systematic review. Useful resources are introduced throughout the session.

Cochrane Library is a collection of databases with high-quality systematic reviews, randomized controlled trials and clinical answers. It offers simultaneous search of variety of resources to provide independent evidence to inform healthcare professionals in their decision making. This class will introduce the variety of resources offered by Cochrane Library, how to search them, and the key features of the search platform.

This class will explore best practices for planning and conducting literature searches. The topics and tips introduced in this session are intended to support general literature searching practices that participants can use to conduct more effective searches, regardless of database used. This class will address the importance of the literature search, introduce a basic framework to help develop search strategies, discuss how to connect concepts and use other search helpers in your strategies, and explore resources and tools that support good literature searching practices. 

Gray literature is not controlled by commercial publishers and usually is not peer reviewed. However, gray literature can help identify useful information outside the published, peer reviewed articles through reports, dissertations, conference abstracts, official documents, research-in-progress, and clinical trials. It might get you information you would never find in traditional sources. This workshop will focus on how to find credible gray literature for your research topic or for part of a systematic review.

During the COVID-19 pandemic, the number of rapid reviews increased and became a popular method of conducting a rigorous literature review, using systematic review methodology in a shorter time frame. This type of review helps synthesize the available evidence in a narrative descriptive format and can be done at a faster pace than a full systematic review. The introductory class will discuss what research questions are best suited for a rapid review, best practices for their conduct, and review the required methodological steps on how to conduct an effective rapid review. 

A scoping review is a preliminary assessment of research literature that aims to systematically map the literature, clarify concepts, and identify the evidence and knowledge gaps on a topic. This research method can be conducted as standalone review or used as an initial step before conducting a full systematic review. Participants will learn best practices, tips, and guidelines on how to conduct a scoping review. This introductory class will also include scoping review resources and an overview of NIH Library research support services.

Conducting a systematic review can be time consuming and challenging. This class provides an overview of the different steps in the comprehensive process of conducting a systematic review. At the completion of the class, participants will be able to identify each step of the systematic review process and know where to access valuable resources.

Umbrella reviews, sometimes referred to as review of reviews, are a review of other published systematic reviews and meta-analyses and are appearing more frequently in scientific literature. Umbrella reviews appropriately address a broad question on a topic when there are plenty of published reviews already available. The benefits of conducting an umbrella review are to help synthesize the evidence for decision making in healthcare and explore inconsistencies and biases.

You aren’t sure which type of literature review would best match your research question, or maybe you didn’t realize there were so many kinds of reviews. Join us for an overview of literature review types and their purposes. By the end of this session, attendees will be able to describe the purpose of a literature review, differentiate among five types, and select the right review for your research goals.

The purpose of this class is to introduce the fundamentals of conducting a meta-analysis. The focus will be on randomized clinical trials; however, the presenter will also briefly discuss the application of meta-analyses in laboratory and observational (epidemiological) studies. 

This class will define retractions and discuss their effects on evidence synthesis products such as systematic reviews. Participants will explore the impact and consequences of retractions through a case study along with data from the literature. Additionally, participants will learn about how to incorporate identification of retractions into the evidence synthesis process. This class is recommended for anyone who wants a more in-depth analysis of retractions beyond what is covered in the Retractions: An Introduction class.

Do you want to write a review, but not sure what type of review would be best for your research question or topic? In today’s research environment, everyone seems to be doing a review of some type, especially systematic reviews.  However, not all literature reviews are systematic reviews, nor need to be. There are many other types of evidence-based reviews. This session will explore the various literature review types, the associated methodologies of each, and how to select the best option for you.

Covidence is a web-based tool that can be used in conducting systematic and scoping reviews, and meta-analyses. This tool helps researchers manage article screening at the title, abstract, and full text levels. This class covers the basic features of Covidence, including setting up a review, importing and exporting records, and screening. Data extraction, quality assessment, and additional resources will be covered. At least one member of the research team must be based at the NIH to gain Covidence access.

This class will provide an overview of the various reporting guidelines and standards established for conducting reviews and how to use them in the writing of your review manuscript. Participants will also gain valuable information about how to structure their manuscript and select appropriate journals for submission.
