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
backgroundPatients receiving massive transfusion after acute hemorrhage are at risk for transfusion-related acute lung injury (TRALI), a severe complication. Neutrophil extracellular traps (NETs) play a key role in acute lung injury. This study aimed to explore the link between NETs and TRALI and to develop a risk-prediction model using machine learning for early detection and intervention.
methodsIn this multicenter prospective study, 513 patients with acute massive hemorrhage who underwent transfusion therapy (March 2020-February 2025) were consecutively recruited. All biomarker assays, sampling time points, and the statistical analysis plan were prespecified and ethically approved before study initiation. Based on TRALI occurrence after transfusion, they were divided into an injured group (n = 42) and a uninjured group (n = 471). Clinical features and NET-related markers were compared. LASSO regression was used for variable selection, followed by random forest for importance ranking. Multivariate logistic regression identified independent predictors, and a nomogram model was built and evaluated using ROC analysis, calibration, and decision curve analysis.
resultsThe injured group had significantly higher rates of smoking history, total infusion volume, perioperative transfusion volume, and transfusion frequency (all p < 0.05). Levels of citrullinated histone H3 (citH3), myeloperoxidase (MPO), neutrophil elastase (NE), interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interleukin-8 (IL-8) were also elevated (all p < 0.05). LASSO identified seven key variables, with citH3 and MPO showing high importance. Multivariate analysis confirmed citH3 (OR = 1.142), MPO (OR = 5.017), and NE (OR = 1.014) as independent predictors of TRALI (all p < 0.05). The combined model achieved an AUC of 0.85 (95% CI: 0.78-0.92), indicating strong predictive performance.
conclusionTRALI risk in acute massive hemorrhage patients is associated with NET-related markers, particularly citH3, MPO, and NE. A model integrating these indicators provides valuable early identification of TRALI, aiding clinical decision-making.
