Reviews on Long COVID: a scope of the literature.:Update April 2023

Summary • For this update, we identified 37 published reviews and 73 new protocols for ongoing reviews on Long COVID. The number of published reviews is lower than in our last quarterly report in January (n=50), but higher than in our October report (n=29), all of which used the same databases and search strategy. • Most published reviews were focused on symptoms or effects, which is consistent with the earlier reports. • We identified fewer published reviews with a primary focus on Long COVID risk factors (3/37) than in January (10/50). • Most of the protocols for ongoing reviews focused on Long COVID treatment or rehabilitation (30/73), as was the case in the January report (33/56). • Most of the other protocols focused on symptoms or effects (21/73), or risk factors (13/73).
