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 viruses (IAV) pose substantial burden on human and animal health. Avian, swine and human IAV bind sialic acid on host glycans as receptor, whereas some bat IAV require MHC class II complexes for cell entry. It is unknown how this difference evolved and whether dual receptor specificity is possible. Here we show that human H2N2 IAV and related avian H2N2 possess dual receptor specificity in cell lines and primary human airway cultures. Using sialylation-deficient cells, we reveal that entry via MHC class II is independent of sialic acid. We find that MHC class II from humans, pigs, ducks, swans and chickens but not bats can mediate H2 IAV entry and that this is conserved in Eurasian avian H2. Our results demonstrate that IAV can possess dual receptor specificity for sialic acid and MHC class II, and suggest a role for MHC class II-dependent entry in zoonotic IAV infections.
