Scoping review of COVID-19-related systematic reviews and meta-analyses: can we really have confidence in their results?

Conclusion
The methodological and reporting quality of current COVID-19 SR is far from optimal. In addition, most of the current SRs fail to address relevant threats to their internal validity, including repeated patients and heterogeneity in the definition of severe COVID-19. Adherence to proper study design and peer-review practices must remain to mitigate current limitations.
