Choosing Between Extraction 1 and Extraction 2 in Covidence

Posted on by

Here’s a tip for getting the most out of data extraction in Covidence.

For background, the MSK Library has an institutional account to Covidence, an online software platform used for systematic and other related reviews. Covidence offers teams a collaborative space to screen, appraise, and extract data from articles, and our institutional account means anyone at MSK can use this platform for their review projects.

Once you’re within the Covidence page for your review, you’ll see there are four stages below Review Summary, with Extraction at the end. When you click on Settings to the right of Review Summary, you’ll have the option of selecting between Extraction 1 and Extraction 2.

Both extraction options offer a customizable data extraction template, so which to choose?

Covidence offers the FAQ: How to decide when to use Extraction 1 vs Extraction 2.

  • Extraction 1 is designed for intervention reviews with a standardized PICO(T) structure, as it offers a structured format for organized data collection, which makes meta-analysis easier. This structure allows it to automatically fill in data extraction fields with suggestions you can review. Results can be exported to CSV, Excel, and RevMan.
  • Extraction 2 offers an unstructured format for flexible data collection and is fully customizable. It doesn’t offer automated extraction suggestions and only exports to CSV.

Learn more about data extraction and templates for these two options in the Covidence Knowledge Base. If you prefer to be hands-on, Covidence offers a demo review, and you can test both extraction options there before choosing which one is best for your project.

New Systematic Review Service Guide

Posted on by

A screenshot of the first half of the Introduction page of the Systematic Review Service guide.The MSK Library Reference Team has launched a new guide to our Systematic Review Service!

We approached this guide with our users in mind, building it with the questions we most frequently get about systematic and other related reviews.

You can use this resource to get a sense for what review type is right for you, request to work with an MSK librarian, or learn from our step-by-step breakdown of the systematic review process. Throughout the guide we’ve emphasized the support you can expect from the MSK Library while working on your research project.

If you’re thinking about embarking on a review, we encourage you to explore it! We look forward to partnering with you in the future.

Andrew Vickers, PhD, Attending Research Methodologist, Epidemiology & Biostatistics, MSK
Dr. Vickers’ research falls into three broad areas: randomized trials, surgical outcomes research and molecular marker studies. A particular focus of his work is the detection and initial treatment of prostate cancer. Dr Vickers has analyzed the ’learning curve’ for radical prostatectomy. He is working on a series of studies demonstrating that a single measure of prostate specific antigen (PSA) taken in middle age can predict lethal prostate cancer up to 30 years subsequently. He has also developed a statistical model to predict the result of prostate biopsy, work that has been commercialized and is clinically available through OPKO Diagnostics. His work on randomized trials focuses on methods for integrating randomized trials into routine surgical practice so as to compare different approaches to surgery. As part of this work he has pioneered the use of web-interfaces for obtaining quality of life data from patients recovering from radical prostatectomy. Dr. Vickers’ methodological research centers primarily on novel methods for assessing the clinical value of predictive tools. In particular, he has developed decision-analytic tools that can be directly applied to a data set, without the need for data gathering on patient preferences or utilities. Dr Vickers has a strong interest in teaching statistics. He is course leader for the MSK biostatistics course and is author of the introductory textbook “What is a p-value anyway?” In his capacity as Co-Director of the PRO-CEL Core Facility, Dr. Vickers spearheads a number of innovative informatics initiatives throughout MSK, including the Amplio quality assurance system. He attended his first Cochrane Collaboration meeting in 1995 and has worked on systematic reviews since 1994.
