1 · What the graph read from it

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.

2 · The registry

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

Purpose: This study investigated the viral genomic characteristics of infants and young children who presented to our hospital with gastrointestinal symptoms during a local COVID-19 epidemic and were confirmed to have SARS-CoV-2 infection. Patients and methods: Between May and August 2025, pharyngeal swab samples were collected from four infants and young children who presented to the outpatient department of Meizhou People's Hospital in Meizhou, with gastrointestinal symptoms. Nucleic acid testing and whole-genome sequencing were performed. The viral mutation profile was analyzed, and the potential impact of mutations on protein function was predicted. Results: Pangolin typing identified the NB.1.8.1 variant in three patients and the PQ.2 variant in one patient. Genome sequences from three of the four viral variants displayed varying degrees of mutation. The nonsynonymous mutations for both variants were concentrated in the spike protein. A comparison with the parental XDV.1.5.1 lineage revealed 14 specific mutations, with 7 nonsynonymous sites conserved across all gene sequences. Five of these mutation sites, Conclusion: SARS-CoV-2 variants from specimens obtained from four infants and young children exhibited varying degrees of mutation, providing evidence for the ongoing evolution of emerging variants in pediatric patients. However, monitoring genomic changes of circulating variants requires further clinical specimens, which contributes to understanding the dynamic changes at mutation sites, thereby supporting epidemic prevention and control.
