Molecular Epidemiological Characteristics of Gastroenteritis Outbreaks Caused by Norovirus GII.4 Sydney [P31] Strains - China, October 2016-December 2020.
Article in China CDC weekly, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
introductionHuman noroviruses are the leading cause of acute viral gastroenteritis (AGE) worldwide in all age groups. GII.4 strains have been the predominant genotype circulating globally over the last 2 decades and since 2012. GII.4 Sydney viruses have emerged and caused the majority of AGE outbreaks worldwide.
methodsData from norovirus outbreaks from the laboratory-based surveillance of norovirus outbreaks in China (CaliciNet China) between October 2016-December 2020 were analyzed.
resultsDuring October 2016-December 2020, 1,954 norovirus outbreaks were reported, and positive fecal samples from 1,352 (69.19%) outbreaks were genotyped. GII.4 Sydney [P31] viruses accounted for 2.1% (October 2016-August 2017), 5.5% (September 2017-August 2018), 3.3% (September 2018-August 2018), 26.6% (September 2019-August 2020), and and 1.1% (September 2020-December 2020) of GII outbreaks, respectively. Compared to reference strains of GII.4 Sydney [P31] from 2012 to 2013, 7 amino acid mutations in epitopes[A (297, 372 and 373), B (333), E (414), and H (309 and 310)] and 1 in human histo-blood group antigens binding site at site II 372 were found by analyzing 9 GII.4 Sydney [P31] complete genomic sequences.
conclusionsThis report identified the genomic variation of GII.4 Sydney [P31] from CaliciNet China. Continued surveillance with prompt genotyping and genetic analysis is necessary to monitor the emergence of novel GII.4 variants.
