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
Nipah virus (NiV) is an emergent paramyxovirus that causes serious disease in humans and animals. Accurate quantification of neutralizing antibodies (nAB) against NiV is essential for vaccine development. The current standard, the plaque reduction neutralization test (PRNT), requires authentic infectious NiV and BSL-4 containment, taking 4-7 days to complete. In this study, we developed a hybrid alphavirus-Nipah virus pseudovirion (Ha-NiV) composed of a non-replicating Nipah virus virus-like particle (VLP) that encapsulates an RNA genome from a fast-expressing SFV (Semliki Forest Virus) alphaviral vector. Ha-NiV can infect NiV target cells but is replication incompetent, enabling rapid quantification of nAB (6-18 h) in BSL-2 conditions. We demonstrated concentration-dependent neutralization of Ha-NiV using an anti-NiV F glycoprotein antibody, 12B2, which is induced with a prefusion stabilized NiV F ectodomain trimer. We further validated the Ha-NiV-based neutralization assay using sera from Nipah virus-infected African green monkeys, and established a good correlation (
