| Aim | To assess the methodological quality (AMSTAR-2) and reporting quality (PRISMA 2020) of COVID-19 living systematic reviews indexed across Medline, Embase, Cochrane Library, China national knowledge infrastructure, Wanfang Database, and China Science, Technology Journal Database (VIP) from inception until December 9, 2021, with additional searches conducted on May 13, 2022. |
| Level of Investigation | Analytical |
| Summary of Findings | From 64 included living systematic reviews of COVID-19 indexed across Medline, Embase, Cochrane Library, China national knowledge infrastructure, Wanfang Database, and China Science, Technology Journal Database (VIP) from inception until December 9, 2021, with additional searches conducted on May 13, 2022. 21.9% of the 64 living systematic reviews of COVID-19 were rated as "high", 4.7% as "moderate", 23.4% as "low", and 50% as "critically low" methodological quality according to AMSTAR-2. For reporting quality (PRISMA 2020) "Certainty of evidence" had the worst reporting quality, with only 41% of COVID-19 reviews fully reporting it. The number of included studies, and registration were associated with AMSTAR-2 levels. |
