Prevalence, Molecular Epidemiology, and Clinical Characteristics of Human Bocavirus Among Patients with Acute Gastroenteritis in Northern Brazil During 2017-2022.

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
Acute gastroenteritis (AG) is a major illness in early childhood. Recent studies suggest a potential association between human bocavirus (HBoV) and AG. HBoV, a non-enveloped virus with a single-strand DNA genome, belongs to the Parvoviridae family. This study aimed to describe the frequency of HBoV in Northern Brazil using samples from patients with AG collected between 2017 and 2022. Fecal samples obtained from the viral gastroenteritis surveillance network at the Evandro Chagas Institute (IEC) were analyzed. Fecal suspensions (20%) were prepared, and the viral genome was extracted. PCR and nested-PCR were employed to detect HBoV, followed by nucleotide sequencing to identify viral types. Out of 692 samples, HBoV positivity was detected in 9.2% of cases (64/692). Genotypes HBoV-1, HBoV-2, HBoV-3, and HBoV-4 were found in 42.5% (17/40), 22.5% (9/40), 32.5% (13/40), and 2.5% (1/40) of the specimens, respectively. Co-infections with HBoV and other enteric viruses occurred in 48.3% (31/64) of cases, with RVA being the most frequent (31.2%, 20/64). The study results underscore the importance of continuous monitoring and further research to better understand the seasonality, coinfection patterns, and genetic variability of HBoV.
