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

backgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has spread rapidly worldwide since its emergence in 2019. While infections in children are generally mild, severe disease can occur in some rare cases. Herein, we aim to identify risk factors for severe disease in children hospitalized with SARS-CoV-2 infection during the post-Omicron period.

methodsThis retrospective cohort study was based on a review of the records of children aged under 15 years hospitalized with SARS-CoV-2 infection at a university hospital in Xi'an, China between December 8, 2022, and January 17, 2023. Multivariable logistic regression was applied to identify factors associated with severe disease.

resultsOf 164 children included in the analysis, 33 had severe disease and 131 had non-severe disease. Disease severity did not differ significantly according to sex or SARS-CoV-2 vaccination status. The prevalence of comorbidities was significantly higher in children with severe disease than in those with non-severe disease (30% [10/33] vs. 10.7% [14/131], p = 0.04). The prevalence of neurological manifestations and multisystem disease were also significantly higher in children with severe disease than in those with non-severe disease (91% [30/33] vs. 27.5% [36/131], p = 0.001; and 64% [21/33] vs. 43.5% [57/131], p = 0.039, respectively). Multivariable logistic regression analysis identified younger age (odds ratio [OR]: 0.702, 95% confidence interval [CI]: 0.551-0.893; p = 0.004), the presence of comorbidities (OR: 9.042, 95% CI: 2.505X-32.645; p = 0.001), and neurological signs (OR: 217.21, 95% CI: 34.988-1348.469; p < 0.001) as independent risk factors for severe disease.

conclusionThis single-center retrospective cohort study reveals that younger children with comorbidities and neurological manifestations are at higher risk of developing severe SARS-CoV-2 infection. These findings should be interpreted considering limitations including short study timeframe, homogeneous vaccine types, and lack of variant-specific analyses.
