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

In the face of severe outcomes from COVID-19, vaccines have proven immunogenic and safe and are strongly recommended during pregnancy. This study examines the effects of maternal COVID-19 vaccination on physical development, behavior, and neurogenesis in mouse offspring. After inoculation with inactivated SARS-CoV-2 vaccine (Vero Cell) at gestational day 14.5, antibodies were detected in the serum of dams and pups. At one month of age, offspring of vaccinated dams-but not controls-showed enhanced working memory, increased neural proliferation, neuroblast formation, stem cell activity, and more mature neurons in the dentate gyrus (DG). Luminex assay showed elevated hippocampal IFN-γ and CX3CL1, both linked to neurogenesis and memory. Conditional knockout experiments identified microglial IFNγR1 and CX3CR1 as key mediators of neuronal development through regulating microglial activation and chemotaxis. These findings suggest maternal SARS-CoV-2 vaccination transiently enhances hippocampal neurogenesis and working memory in offspring, without causing neurodevelopmental risk.
