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

Innate immune responses trigger the development of adaptive immune responses through the production of cytokines. In the present study, we compared the cytokine production in mice inoculated with a novel replicon mRNA COVID-19 vaccine. Biphasic and prolonged IFN-γ production was observed after the first dose, and sustained production was observed after the second dose, whereas conventional mRNA vaccines induced a peak of IFN-γ production only on Day 1 after both first and second inoculations. These findings may be associated with the self-replicating properties of the replicon mRNA vaccine following inoculation.
