This meta-analysis aimed to find the effect of variable domain of heavy-chain antibodies (VHHs) for the treatment of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in animals. The databases of the PubMed, China National Knowledge Infrastructure (CNKI), Wan fang data, Cochrane Library, and Embase were searched for articles published before August 2022 on the protective effects of VHHs in animals. The articles retrieved were screened using inclusion and exclusion criteria. The data were analyzed using Review Manager 5.4. Six articles were selected from 667 articles based on the inclusion and exclusion criteria in VHHs. A forest plot showed that VHHs could offer protection against SARS-CoV-2 infection in animals [Mantel-Haenszel (MH) = 172.94, 95% confidence interval (CI) = (43.96, 678.42), P < 0.00001]. There was almost no heterogeneity in this study (I2 = 0). A funnel plot showed that the bias of the data analysis was small. This is a special meta-analysis proved that VHHs could treat and prevent SARS-CoV-2 in animals.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
