Epidemiology and genetic diversity of norovirus GII genogroups among pediatric patients in Beijing, China, during 2023-2024.
Article in Virology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundNorovirus is an important cause of viral acute gastroenteritis (AGE) worldwide.
methodsIn order to characterize the molecular epidemiology and genetic diversity of norovirus in children in Beijing, 3634 anal swab samples of AGE patients from January 2023 to December 2024 were analyzed. Norovirus was detected using RT-PCR and genotyped by sequencing the partial RdRp and VP1 region.
resultsDuring the two-year period, norovirus was detected in 19.6% of AGE cases, with the highest detection rate in children under 3 years of age. GII.4 and GII.P16 were the dominant genotypes of VP1 and RdRp, with a detection rate of 36.39% and 44.59%, respectively. According to the dual-typing system combined the RdRp and VP1, the dominant genotypes of norovirus changed between 2023 and 2024. In 2023, the most common genotype was GII.3[P12] (39.15%), followed by GII.4 Sydney[P16] (32.34%) and GII.4 Sydney[P31] (15.32%). However, in 2024, the dominant genotype was GII.17[P17] (41.43%), followed by GII.4 Sydney[P16] (34.29%) and GII.3[P12] (20.0%). The GII.17 variants in this study were divided into two clusters: cluster IIIa and IIIb, which shared high nucleotide identity with GII.17 variant emerged in 2014/2015. Significantly, GII.4 Sydney[P31] and novel GII.4 Sydney[P16] variants co-circulating in this region from 2023 to 2024.
conclusionThe data provided useful information on the molecular epidemiology of norovirus in sporadic AGE among children and highlighted the necessary to continuously monitor the epidemiological characteristics of norovirus associated AGE.
