Choosing Between Extraction 1 and Extraction 2 in Covidence

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

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.

Important NCBI Account Changes Coming in June: Choosing Your Best Third-Party Option

NCBI announced it will transition to federated account credentials on June 1, 2021. What does this mean for you?

We’ve noted before that creating a My NCBI account is a key tool within PubMed and other NCBI databases. It retains your user information and database preferences to help you keep track of research, customize your search experience, and stay compliant with the NIH Public Access Policy. While these account changes are being implemented for privacy and security reasons, they won’t affect what you’ve stored within your NCBI account. Look to the NCBI Account Login Changes FAQs page for more information.

Starting now, if you only have a Native NCBI Account (a NCBI username and password), you will need to add a Linked Account to it. This means signing in via a third-party organization, and letting it confirm your identity. This will give you federated account credentials within NCBI, and make your account more secure. Examples of organizations that you can link through are eRA Commons, Google, ORCiD, Login.gov, Microsoft, Facebook, and NIH.

As there are 4,000+ third-party login options to choose from, it’s important you select what works best for you. See this list for a breakdown of recommendations by role, activity, or preference. Here are two common scenarios for our MSK user community:

If your work involves using NCBI within the grant application process:

If your work involves using NCBI as a researcher or clinician:

Below are instructions for adding your chosen third-party option(s). The Library recommends adding at least two in case one is disrupted.

Instructions to add a Linked Account from the main NCBI page:

  1. Go to NCBI
  2. Select an option from the list or click on “more login options” for all organizations listed alphabetically

If you’d like to add more Linked Accounts once logged in to NCBI:

  1. Click on your NCBI username in the upper right corner
  2. Select Account Settings
  3. Under Linked Accounts, select Change
  4. In the search box, search for and select your desired account
  5. Authenticate with the third-party
