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

Influenza A virus (IAV) causes annual epidemics and sporadic pandemics of acute respiratory infections resulting in significant morbidity and mortality. Although approved influenza antivirals (e.g., oseltamivir and baloxavir) exist, concerns persist about the potential for emergence of drug-resistant variants, highlighting the continuing need for new antiviral therapies. Here, we describe the development of an orally bioavailable, direct-acting antiviral (VNT-101) with a novel mechanism of action: disrupting homo-oligomerization of the influenza nucleoprotein (NP) and thereby inhibiting viral RNA synthesis. Selection of drug-resistant mutants revealed amino acid substitutions mapping to the oligomerization domain of NP, and X-ray crystallography co-structure determination of VNT-101 complexed with recombinant NP confirmed VNT-101 binding in the oligomerization pocket. Biochemical experiments using size exclusion chromatography confirmed disruption of oligomerization when this chemotype is added to preparations of recombinant NP
