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

Current antiviral therapies for orthopoxviruses face critical challenges, including limited efficacy and significant toxicity, which impede outbreak containment and clinical management. Here, we identify lactoferrin as a potent antiviral agent against multiple orthopoxvirus strains. Combination administration of lactoferrin with brincidofovir or tecovirimat demonstrated additive efficacy, suggesting a potential clinical strategy to reduce individual drug toxicity. Mechanistically, lactoferrin blocks viral entry by competitively binding to heparan sulphate proteoglycans (HSPGs). It also suppresses viral replication by regulating host antiviral pathways, including down-regulating cytokines and upregulating TGF-β-dependent antiviral signalling pathways. We identify TGFBI as a virus-responsive target regulated by lactoferrin. Lactoferrin treatment restores TGFBI expression and activates downstream MAPK/ERK and JAK2/STAT3 signalling cascades, leading to enhanced interferon production and interferon-stimulated gene (ISG) expression. In a murine vaccinia virus (VACV) infection model, lactoferrin treatment reduced lung viral loads and histological damage. These results underscore lactoferrin's distinctive dual antiviral mechanism and highlight its translational potential as a safe and cost-effective prophylactic or therapeutic agent. It is particularly beneficial for immunocompromised populations in resource-limited settings during orthopoxvirus outbreaks.
