IFN-λ4 Exhibits Differential Induction and Antiviral Activity in RSV and HMPV Infections.
Article in Viruses, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Interferons (IFNs) are essential mediators of the innate immune response to viral infections. Among the type III IFNs, the role of IFN-λ4 in respiratory viral infections remains largely understudied. Respiratory syncytial virus (RSV) and human metapneumovirus (HMPV) are clinically significant pneumoviruses that elicit divergent IFN responses in epithelial cells. Here, we investigate the virus-specific induction and antiviral activity of IFN-λ4 by HMPV and RSV infections. We demonstrate that RSV induces a limited expression of IFN-λ4, which is regulated by the expression of the NS1 protein. Furthermore, RSV and HMPV rely primarily on RIG-I for IFN-λ4 induction. Finally, we show that IFN-λ4 exerts antiviral activity against both viruses, with RSV displaying greater sensitivity. These findings highlight the antiviral role of IFN-λ4 to clinically relevant respiratory viruses.
