Novel Biomarkers for Improving the Diagnosis of Appendicitis in Pediatric Patients.
Article in Journal of clinical laboratory analysis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionDiagnosing appendicitis in pediatric patients remains a clinical challenge, especially in resource-limited settings where imaging tools are less accessible. Inflammatory markers, including the Neutrophil-to-Lymphocyte Ratio (NLR), Monocyte-to-Lymphocyte Ratio (MLR), Neutrophil-to-Monocyte Ratio (NMR), Platelet-to-Lymphocyte Ratio (PLR), Neutrophil-to-Platelet Ratio (NPR), and C-reactive protein (CRP), offer a promising approach to enhancing diagnostic accuracy. We aimed to evaluate the utility of these inflammatory markers to diagnose appendicitis.
methodsThis retrospective study included 1027 pediatric patients who underwent appendectomy, with appendicitis confirmed histopathologically in 891 cases. Preoperative Inflammatory markers (NLR, MLR, NMR, PLR, NPR, and CRP) were analyzed and optimal cutoff values were determined using Receiver Operating Characteristic (ROC) curves.
resultsElevated NLR, NMR, PLR, NPR, and CRP were strongly associated with appendicitis, while an inverse relationship was observed with MLR. NLR (≥ 4.42) and NPR (≥ 0.0327) demonstrated high diagnostic accuracy with sensitivity and specificity exceeding 75%. Surprisingly, MLR showed a statistically significant inverse relationship with AA risk. Temperature differences between groups were not statistically significant.
conclusionEach suggested novel inflammatory marker has the potential to improve the preoperative diagnosis of appendicitis in pediatric patients. Such a system could minimize reliance on imaging and expedite decision-making, especially in resource-constrained settings. Further prospective studies are needed to validate these findings and explore their clinical utility.
