Elevated neutrophil extracellular traps predict mortality and CKD progression in critically ill AKI patients: a prospective observational study.
Observational study in International urology and nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundInflammation plays a pivotal role in the pathophysiology of acute kidney injury (AKI), mediating tubular damage, systemic complications, and modulation of kidney repair. Neutrophil extracellular traps (NETs) have emerged as key mediators of inflammation and tissue injury, though their role in AKI is not yet fully defined.
aimsThis study aimed to evaluate NET levels in critically ill AKI patients and assess their association with disease severity, clinical outcomes, and progression to chronic kidney disease (CKD).
methodsIn this prospective observational study, 73 critically ill AKI patients and 33 age- and sex-matched healthy controls were enrolled. NET levels were measured via ELISA at admission and post-recovery. Correlations with AKI severity (KDIGO stages), inflammatory markers (CRP, WBC), and clinical outcomes (mortality, ICU stay, CKD progression) were analyzed.
resultsNET levels were significantly higher in AKI patients compared to controls (median: 364 vs. 264 pg/mL, p < 0.001) and correlated with AKI severity, APACHE II scores, and mortality. Elevated NETs predicted CKD progression (AUC = 0.919) and mortality (AUC = 0.855). Non-survivors had 82% higher median NETs at admission (571 vs. 313.5 pg/mL, p < 0.001), and persistent NET elevation post-recovery suggested ongoing subclinical inflammation.
conclusionsNETs are elevated in AKI and independently predict CKD progression, infection risk, and mortality, supporting their use as dynamic prognostic biomarkers and potential therapeutic targets..
