PMID: 33577987.

Noteworthy Changes in the PRISMA 2020 Update

Among the key PRISMA 2020 guideline changes are: more inclusive wording so that it’s more accommodating to other methods from different fields (ex., methods beyond randomized trials of health interventions); some of the categories have been broken down into more granular sub-items that are more explicit and provide more clarity about what exactly should be reported, some new items and sub-items have been introduced or expanded upon; and some of the items have been slightly re-ordered in the checklist.

The new PRISMA 2020 guideline is meant to reflect the changing reality of the current research climate. For example, now that more people are registering their protocols as is recommended by PRISMA, there is a sub-item added to address the clear reporting of potential protocol amendments. Also – in line with the open science movement, there are sub-items related to reporting about the availability of data and statistical code, etc. Furthermore, with automation tools starting to be considered for use in SRs, more explicit reporting in this area is also recommended, as well as the reporting of conflicts of interest of review authors, something which is becoming a more common requirement in all areas of scholarly publishing.

There also has been an obvious push towards greater transparency in the methods, with recommendations to include the full search strategies and number of results for all information resources searched (which is in accordance with the PRISMA-S extension also published this year), as well as to provide the full citations for all of the included studies and citations for the studies that were excluded at the full-text stage, with reasons.

This latest version of PRISMA also appears to recognize that often in SRs, the synthesis of the results includes the grouping or sub-grouping of studies for the analysis, which the guideline suggests should be better reported upon. PRISMA 2020 makes a more explicit request for the reporting of criteria and processes used to group studies. Related to this, PRISMA 2020 also encourages that the reporting of characteristics and risk of bias be handled not for all included studies as a whole but rather to be considered among sub-grouped studies contributing to each synthesis.


New Tools and Templates for PRISMA 2020

It should be noted that the PRISMA guidelines are recommendations and not every item in the checklist applies to every situation. (In fact, it is for that very reason that PRISMA extensions exist and should still be used in conjunction with PRISMA 2020 as not all of these have been perfectly harmonized as of yet.) As such – this guidance should be viewed as useful suggestions for improving the quality of reporting of a systematic review – keeping in mind, however, that not every item is always applicable and mandatory.

This spirit of flexibility is reflected in the increased template options made available on the PRISMA Statement website to accommodate different scenarios. Both the PRISMA 2020 Checklist and Flow Diagram template options are now available for viewing and downloading. In addition to the PDF and Word templates, Shiny App computer applications have also been created that can be used to more easily generate the completed checklist and flow diagram by inputting data.

Two Types of Author Profiles: Auto-Generated or Opt-In

Posted on by

Author profiles are extremely useful vehicles for increasing the visibility and discoverability of your published work. Although it is more popular in the business world, many researchers now have LinkedIn profiles that they may use to push out information about their research and publications to their professional community.

However, there are also some more scholarly options that are worthy of investigation, as they may increase your chances of having your work discovered online by other researchers who may be interested in building on your research or in engaging with you in scholarly collaboration.

There are two types of author profiles: 1) auto-generated ones and 2) “opt-in” ones.

1) Auto-generated Author Profiles:

In the case of auto-generated Author Profiles, when the author publishes a new work, the database producer will automatically add the new citation record to the profile, without further author involvement needed. All profiles are available for viewing by searchers of the database and often include some research impact metrics. (Note: It is a good idea to periodically check your Scopus and Web of Science database profiles for accuracy as errors may negatively-impact the research impact metrics being reported on your Author Profile.)

Examples:

  • Synapse (MSK Authored Works) – https://synapse.mskcc.org/synapse
    Synapse is a database of citations to MSK-authored works (e.g., journal articles, meeting abstracts, book chapters, etc.) that includes some traditional research metrics and alternative metrics (embedded/sourced from a vendor called Dimensions).

  • Scopus Author Profiles – https://libguides.mskcc.org/scopus
    Scopus Author Profiles include metrics (e.g. H-Index) that are generated via citation analysis of the contents of the Scopus database, which includes “Times Cited” data.

  • Web of Science Author Profiles – https://libguides.mskcc.org/webofscience
    Similar to Scopus Author Profiles, however, the new version of Web of Science will include additional details that may speak to an individual author’s research impact, for example, Author Position information (First or Last author, etc.).

2) Opt-In Author Profiles:

In the case of opt-in Author Profiles, the author can choose to register for an account with a particular service and create a profile. It is the author’s responsibility to add citations to the profile and to update it whenever they publish new works. The author can also decide to make the profile public or private (i.e., they are in control over who/what gets viewed).

Examples:

  • ORCID – https://orcid.org/
    ORCID (Open Researcher and Contributor ID) is an independent, not-for-profit, non-proprietary Author Profile resources that does not provide metrics, a reporting interface, or a collaboration portal, but they enable other organizations to provide these services. Many journal publishers and database providers have started integrating ORCID links/info into their products. For example, the ORCID symbol is often included as a hyperlink (on HTML and PDF of articles) that leads to that author’s ORCID profile, allowing readers of this paper to immediately discover other works by that author.

  • Publons (via Web of Science) – https://publons.com/about/home/
    The source of research impact metrics data in this resource is its sister product, Web of Science. A unique feature of Publons is that it allows authors to get verified credit for their participation in the peer-review process.

  • Google Scholar – https://scholar.google.com/
    Google Scholar’s greatest advantage is that it is free and not behind a paywall, as are Scopus and Web of Science.

ORCID@MSK App

Since your ORCID profile is “opt-in”, it is not automatically updated with your new works. Recognizing that keeping opt-in Author Profiles up-to-date can be time-consuming, the MSK Library has created an app that makes it easy to push items from your “auto-generated” Synapse profile to your “opt-in” ORCID profile. You can use the ORCID@MSK app to connect your Synapse profile to your ORCID profile. Since Synapse is automatically updated, you can periodically login to ORCID@MSK and pass on the new items added to Synapse to your ORCID profile so that it also stays up-to-date.

New MSK LibGuide on COVID-19

Posted on by

Over the last year, the impact of the COVID-19 pandemic has been felt by everyone in all walks of life, across the planet. It is not surprising, therefore, that the amount of COVID-19 related information available, both scholarly and not, has continued to grow exponentially.

With over 5,000 trials registered in ClinicalTrials.gov, over 120,000 openly-available journals article in PubMed Central (PMC), over 110,000 records in PubMed, over 2,000 COVID-19 related systematic reviews or meta-analyses, and even 296 publications by MSK authors (as of 3/11/2021), efforts to organize this information and make it more discoverable couldn’t be more welcome.

Thanks to the savvy information evaluation and organization skills of MSK Library Research Informationist, Kendra Godwin, the MSK community and the public at large can now take advantage of the Library’s new COVID-19 LibGuide to discover the plethora of COVID-19 resources and tools available online.

The MSK Library COVID-19 LibGuide includes resources arranged across nine tabs/sections:

  • Home
  • Local Resources
  • Resource Collections, News, and Trackers
  • Literature
  • Mental Health and Workplace Safety
  • Equity, Ethics, and Communication
  • Guiding Clinical and Cancer Care
  • Research, Data, and Visualizations 
  • Information for Cancer Patients and Caretakers

Included resources come from sources ranging from the Centers for Disease Control and Prevention (CDC), to scholarly publishers, professional organizations, public and private institutions, etc., that are both national and international. This finding aid will hopefully help fulfill a variety of information needs, both work-related and personal.
