1 · What the graph read from it

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.

2 · The registry

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

Vaccinia virus enters host cells through a multi-component entry-fusion complex (EFC) that is structurally distinct from canonical viral fusion systems. Understanding how vaccinia virus EFC mediates membrane fusion is crucial for elucidating poxvirus entry and identifying potential antiviral targets. Here, we report the solution NMR structure of a truncated ectodomain of vaccinia J5 protein, residues 2-68. Using recombinant vaccinia viruses expressing J5 mutants, we analyzed substitutions in conserved and surface-exposed residues, as well as chimeric constructs between vaccinia J5 and its entomopoxvirus ortholog AMV232. Functional analyses revealed that the conserved P
