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

Vaccines are the primary intervention against influenza. Currently licensed inactivated vaccines focus immunity on viral hemagglutinin (HA). Self-amplifying mRNA (sa-mRNA) vaccines offer an opportunity to generate immunity to multiple viral proteins, including additional neuraminidase (NA). This evaluation of a bicistronic approach for sa-mRNA vaccine development compared subgenomic promoter and internal ribosome entry site strategies and found consistent and balanced expression of both HA and NA proteins in transfected cells. In mice, sa-mRNA bicistronic A/H5N1 vaccines raised potent anti-HA and anti-NA neutralizing antibody responses and HA- or NA-specific CD4+ and CD8+ T cell responses. The addition of NA also boosted the cross-neutralizing response to heterologous A/H1N1. Similar immunogenicity results were obtained for bicistronic seasonal A/H3N2 and B/Yamagata vaccines. In ferrets, sa-mRNA bicistronic A/H1N1 vaccine fully protected lung from infection by homologous virus and showed significant reduction of viral load in upper respiratory tract, warranting further evaluation of sa-mRNA bicistronic vaccine in humans.
