Role of neutrophil elastase in predicting infection among children with chemotherapy-induced febrile neutropenia.
Article in Clinical and experimental pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInfection is a significant cause of death following chemotherapy-induced febrile neutropenia (FN). Neutropenia and compromised neutrophil function are the primary reasons for the decreased defense against infections. PURPOSE: This study aimed to evaluate the significance of neutrophil elastase (NE) in predicting the outcomes of childhood hematological malignancies with FN.
methodsThe study included 64 patients with FN and 64 healthy children matched for age and sex as controls. The patients were selected from the Hematology and Oncology Unit, Menoufia University, Pediatric Department, and Tanta Oncology Institute. Complete blood counts, C-reactive protein (CRP) levels, NE levels, and blood cultures for bacteria and fungi were performed.
resultsThe levels of CRP and NE were increased among children with FN; of them, 21.9% had Gram-negative bacteremia, 17.2% had Gram-positive bacteremia, and 3.1% had Candidemia. NE level was increased in patients with bacterial infections, with a significant positive correlation with duration of FN. NE level had a cutoff of 6.5, with an area under the curve of 0.899, sensitivity of 83.33%, and specificity of 87.50% signifying a higher risk of mortality compared to other variables.
conclusionNE levels were elevated in children with FN, suggesting its usefulness for the early detection of infection that could decrease infection-related morbidity and mortality.
