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

backgroundAcute kidney injury (AKI) is a common and severe complication in paediatric intensive care units (PICUs), particularly among children with bacterial sepsis. Although the epidemiology of sepsis-associated AKI is well described, reliable biomarkers to predict both its onset and associated mortality are still lacking, limiting their integration into routine clinical practice.

objectiveTo characterise the incidence, clinical phenotype and modifiable risk factors of bacterial sepsis-related AKI in a single-centre PICU cohort and to evaluate the utility of novel biomarkers in refining early risk-stratification.

methodsIn this single-centre retrospective cohort study, data from 475 children admitted to the PICU with severe bacterial infections were analysed. Least absolute shrinkage and selection operator regression and logistic regression analyses were employed to identify biomarkers associated with the occurrence and prognosis of AKI. A nomogram model was developed to facilitate clinical application. The predictive utility of these biomarkers was further validated using receiver operating characteristic (ROC) curve analysis and decision curve analysis (DCA).

resultsAmong the 475 children with bacterial infections, 50 (10.53%) developed AKI. Of these, 20 children died, resulting in a mortality rate of 40%. Regression analysis, model construction and validation through ROC and DCA revealed that elevated cystatin C levels were significantly associated with both AKI occurrence and AKI-related mortality in children with bacterial infections.

conclusionsThis study confirms that elevated cystatin C is a robust predictor of both AKI onset and AKI-related mortality in critically ill children with severe bacterial infections. The nomogram incorporating cystatin C enables early identification of high-risk patients and may support clinical decision-making to improve outcomes.
