What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Pathogenic Middle East respiratory syndrome CoV (MERS-CoV), first identified in Saudi Arabia in 2012, continues to pose a threat to public health. The trimeric spike (S) protein of MERS-CoV binds to the cellular receptor through the receptor-binding domain (RBD) in the S1 subunit to initiate virus entry and infection. Therefore, both the S protein and its RBD are targets for the development of MERS-CoV vaccines. Nevertheless, a direct comparison of the immune efficiency of S- and RBD-based MERS-CoV vaccines has not been made. Here, we compared two mRNA vaccines, respectively, targeting the S (S-mRNA) and RBD (RBD-mRNA) of MERS-CoV for their durable immunogenicity, neutralizing activity, and protective efficacy in a mouse model. Both mRNAs encapsulated with lipid nanoparticles (LNPs) maintained strong stability at various temperatures during the detection period. LNP-encapsulated RBD-mRNA elicited significantly higher and more durable antibodies than LNP-encapsulated S-mRNA, maintaining stronger and broadly neutralizing activity against the MERS-CoV original strain, as well as multiple variants containing key mutations within the RBD region. Importantly, RBD-mRNA provided durable protective efficacy against MERS-CoV infection in middle-aged mice, and this protection was associated positively with serum neutralizing antibody titers. Overall, this study identifies RBD-mRNA as an effective vaccine against MERS-CoV, with great potential for further development.
