Paramyxovirus infection driven by heteromultivalent sialoglycotope binding.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Sialic acids (Sia) on glycoproteins and glycosphingolipids act as receptors for many respiratory viruses, including human influenza A viruses and respiroviruses, which typically bind to α2-6- and α2-3-linked Sia (2-6Sia and 2-3Sia), respectively. In view of this binding discrepancy and as the exact sialoglycoconjugates supporting respirovirus infection remain unclear, we assessed the receptor requirements for infection and binding of several respiroviruses and avian Newcastle disease virus (NDV). To this end, we employed a library of isogenic HEK293 cells displaying defined sialoglycoconjugates. Respirovirus infection was shown to strictly depend on 2-3Sia, with a preference for the terminal Siaα2-3Galβ1-4GlcNAc sialoglycotope regardless of the underlying glycoconjugate structure, whereas NDV showed a broader sialoglycotope usage. Notably, 2-6Sia enhanced respirovirus infection in low 2-3Sia contexts via heteromultivalent surface binding, which resulted in prolonged virus-receptor interactions. This heteromultivalent binding is expected to aid respirovirus infection of the 2-6Sia-rich human upper respiratory tract.
