Epidemiology and genetic diversity of classic human astrovirus with whole-genome sequence analysis in inpatient children under 5 years of age in Yunnan, China.

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
purposeThe aim of this study was to determine the epidemiology, incidence and genetic diversity of classic human astrovirus (HAstV) in inpatient children under 5 years of age for acute gastroenteritis (AGE).
methodsA hospital-based surveillance study was conducted across Yunnan Province to investigate the incidence of HAstV among AGE patients. Viral RNA was extracted from stool samples collected from January 2015 to December 2023 from hospitalized children under 5 years of age with AGE. Demographic and clinical data were collected and analysed. The RNA of eligible stool samples (n = 2501) was screened via real-time RT‒PCR assays for the presence of classical HAstV via a real-time PCR diagnostic kit for rapid detection of HAstV (XABT, China). The positive HAstV samples (Ct < 25) were subjected to next-generation sequencing (NGS), and phylogenetic analysis was performed for genotypic characterization.
resultsA total of 2501 stool samples from hospitalized children < 5 years old were analysed for the presence of classic HAstV from 2015 to 2023. HAstV RNA was detected in 4.88% (122/2501) of the stool samples in the study. There were 1.46 times more male patients than female patients (1484/1017), and their HAstV detection rates were 4.58% (68/1484) and 5.31% (54/1017), respectively, with no statistically significant difference (χ
conclusionThis study provided valuable insights into the epidemiology and genotype diversity of HAstVs in hospitalized children under 5 years of age with AGE. The results can be used in future preventive measurements and the development of effective vaccines.
