This is the 33rd update on Evidence Aid’s COVID-19 project and covers the month to 30 June 2021.


  • Since we started this project in March 2020, we have prepared 540 short, plain language summaries covering more than 840 systematic reviews relevant to the COVID-19 pandemic and its impact.
  • All the summaries are available in English, with most of them also available in other languages including Arabic, Chinese, French, German, Italian, Portuguese and Spanish.
  • The summaries are all freely accessible here along with links to the full reviews.
  • Alongside our summaries for individual reviews, our combined summaries present the evidence from multiple systematic reviews of a single topic in a single summary.
  • We are promoting the summaries through our Twitter, Facebook and Instagram social media feeds and if you’d like to follow us or share the posts, the relevant information is at the end of this update.

In detail:

Systematic review summaries: 540 Evidence Aid summaries are now available on the website, summarising evidence from more than 840 systematic reviews, with 9 new or updated summaries added this month. We now have 52 combined summaries, covering more than 320 reviews, with 1 combined summary added this month.

Among the additions this month are summaries of rheumatic symptoms in COVID-19, whether citizen-centered mobile health apps are useful for collecting spatial data for infectious disease management, what the barriers and facilitators are to electronic consultations in primary care, and a combined summary of the evidence for traditional Chinese Medicine and herbal medicine for COVID-19.

Translations: 536 of the summaries are available in Arabic, Chinese Simplified, Chinese Traditional, French, Portuguese and Spanish, with 336 in Italian and 301 in German.

Literature searches: Approximately 1000 records were screened this month, adding dozens of new reviews to our pending pile, with work ongoing on 28 review summaries and 6 combined summaries.

Volunteers: Our volunteers continue to do amazing work for the project, contributing to searching, screening and downloading reviews, preparing and writing summaries, providing web support, and advising on translations. We’ve had more than 100 volunteers throughout the project, from more than 20 countries.
