Development and characterization of a pseudovirus system for human Aichi virus: in vitro and in vivo analysis.
Article in Virology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Human Aichi virus (AiV) (genus Kobuvirus, family Picornaviridae) has been described as a causative agent of human gastroenteritis since 1989. However, research on AiV at cellular and animal levels is limited. Utilizing a double reporter gene system, we constructed an AiV capsid protein plasmid and genomic backbone Replicon. Subsequently, AiV pseudovirus (AiV PsV) particles were packaged using a three-plasmid co-transfection system. Eleven cell types were screened to identify those susceptible to AiV PsV. Mouse models were established with AiV PsV to determine the optimal mouse species, mode of infection, and detection time, and investigate distribution characteristics of AiVs in vivo. HeLa cells exhibited the highest sensitivity to AiV PsV. A BALB/c mouse model established with bioluminescence imaging performed 24 h after infection via intraperitoneal injection demonstrated that the bioluminescent signal was concentrated in the murine abdominal cavity. The AiV PsV system should advance understanding of the infectious features of AiVs.
