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

A significant numerical increase of genotype GII.17 norovirus-associated sporadic infections was observed in multiple cities in China during the 2024-2025 season. We collected fecal samples from hospitalized children with acute gastroenteritis from 29 sentinel hospitals nationwide to screen for norovirus. A total of 18.7% (n = 412) of the samples tested positive, with a decrease in genotype GII.4 (27% of all positive cases) coinciding with an increase in GII.17 (62%). Comparative phylogenetic analysis of RNA-dependent RNA polymerase and capsid gene sequences revealed that these GII.17[P17] strains were most closely related to strains circulating in the United States and European countries during 2023-2024, with which they shared a recent common ancestor. The evolving epidemiology of norovirus, characterized by the circulation of multiple genotypes, highlights the need for ongoing surveillance and research to better understand its impact and guide the development of vaccines.
