Display of Streptococcus iniae α-Enolase on the Surface of Virus-Like Particles (VLPs) of Nervous Necrosis Virus (NNV) Using SpyTag/SpyCatcher.
Article in Marine biotechnology (New York, N.Y.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Virus-like particle (VLP)-based vaccines are promising candidates for overcoming the safety problems of live vaccines and weak immunogenicity of subunit vaccines. VLPs can be used as a platform for the development of combined vaccines by expressing foreign antigens, and foreign antigens can be displayed on the surface of VLPs by conjugation. In the present study, to use nervous necrosis virus (NNV) VLPs as a delivery tool for Streptococcus iniae α-enolase by displaying on the VLP's surface, the split-intein (SpyTag/SpyCatcher) conjugation system was used. NNV capsid protein fused to SpyTag (Capsid-SpyTag) and S. iniae α-enolase fused to SpyCatcher (α-enolase-SpyCatcher) were recombinantly produced, then mixed in various ratios. A ratio of Capsid-SpyTag to α-enolase-SpyCatcher of 1 to 1.5 showed the highest coupling efficiency corresponding to 83-92% of coupled capsid protein dimer and 32-52% of coupled capsid protein monomer. In TEM observation, VLP of Capsid-SpyTag had a regular shape and size of about 40 nm, while VLP fused with α-enolase-SpyCatcher showed an irregular shape and size of about 40-50 nm in diameter. In preliminary immunization experiments, olive flounder (Paralichthys olivaceus) and zebrafish (Danio rerio) immunized with VLP fused with α-enolase-SpyCatcher showed the lowest cumulative mortality against S. iniae infection.
