Abstract During the COVID-19 pandemic, the urgency for updated evidence to inform public health and clinical care placed systematic literature reviews (SLR) at the cornerstone of research. We aimed to summarize evidence on prognostic factors for COVID-19 outcomes through published SLRs and to critically assess quality elements in the findings’ interpretation. An umbrella review was conducted via electronic databases from January 2020 to April 2022.
