Molecular Characterization of Enteric Viruses Causing Acute Gastroenteritis among Children under 5 Years Old in Distrito Central, Honduras.

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
introductionDiarrheal diseases constitute a significant public health problem in terms of mortality and morbidity. In Honduras and around the world, RVs have consistently emerged as the single most important etiologic agent in acute childhood diarrhea. However, other viruses, such as NoVs and HAstVs, have also been shown to be responsible for viral gastroenteritis. Unfortunately, the country has limited information concerning the etiologic role of these viral agents in acute gastroenteritis. This study investigated the frequency, genotypes, and epidemiological characteristics of RV-A, NoVs, and HAstVs among children under 5 years old in Distrito Central, Honduras.
methodsStool samples and their corresponding epidemiological data were collected from children with acute gastroenteritis in three healthcare centers in Distrito Central. All samples were screened by immunoassays for RV-A and HAstVs. RV-A-positive samples were molecularly characterized by RT-PCR and genotyping assays. RT-PCR was also applied to confirm HAstVs positivity and to detect NoVs, followed by nucleotide sequencing to assign their genotypes.
resultsOur results show that at least one viral agent was detected in 31% of the children. The frequency of RV-A, NoVs, and HAstVs was 14%, 13%, and 5%, respectively. The most frequent RV-A genotype was G2P[4], occurring in 93% of cases. 92.3% of NoVs-positive samples belonged to genogroup II, with GII.4 and GII.16 being the most common. HAstVs were clustered into three genotypes: HAstV-1, HAstV-2, and HAstV-8. Only one sample showed coinfection with NoVs and HAstVs.
conclusionThis comprehensive molecular and epidemiological characterization of enteric viruses demonstrates the vast diversity of these agents and describes for the first time NoVs and HAstVs as causative agents of acute childhood gastroenteritis in Distrito Central, Honduras. This suggests that further in-depth studies of the pediatric population are necessary to develop and implement effective preventive and control measures in the country.
