- •The COVID-19 L·OVE is a free access repository and classification platform.
- •The comprehensiveness and currency of the repository were assessed.
- •We compared it against all the studies included in the SRs published during April 2021.
- •The COVID-19 L·OVE repository is highly comprehensive and current.
- •This evaluation addressed only primary studies and not the other types of articles.
Background and Objective
- •The COVID-19 L OVE repository is highly comprehensive and current. Using as a reference the total number of studies included in a representative sample of systematic reviews, the overall comprehensiveness and currency of the repository were 99.62% and 96.48%, respectively. Both the comprehensiveness and the currency were 100% for randomised trials.
- •The COVID-19 L·OVE repository can be safely used as the sole source for studies in any COVID-19 topic.
What this adds to what is known?
- •The COVID-19 L·OVE can speed up access to evidence without sacrificing quality and therefore encourage timely evidence-informed decisions.
What is the implication, what should change now?
2.1 Methods used to build and maintain the repository
2.2 Methods to assess the performance of the repository
- •Fulfilled the definition of systematic review used in the Epistemonikos database [].
- •Addressed a question directly relevant to COVID-19. We excluded reviews addressing an issue broader than COVID-19. That is, reviews including studies of COVID-19 and other conditions (e.g., other coronaviruses) or using indirect evidence (e.g., evidence from previous pandemics).
- •Clearly reported the search date.
- •Provided the list of included studies.
- •Only included studies published before the search date reported in the review.
