Given the urgent need for credible answers to high-priority questions about the health and social impacts of COVID-19, many systematic reviewers seek to contribute their skills and expertise.
Rather than embarking on unnecessary, duplicate reviews, we encourage the evidence synthesis community to prioritise purposeful replication of systematic reviews of evidence relevant to COVID-19.
We explain why replication of systematic reviews is important, how to carry out a replication, and when to consider replication of reviews.
