Clinical utility of the Platelet-to-neutrophil ratio in differentiating sepsis from neonatal pneumonia: an observational study.
Observational study in Annals of medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundIn some cases, neonates with pneumonia can develop sepsis. The timely and accurate diagnosis of sepsis due to neonatal pneumonia poses a challenge for many clinicians. Therefore, this study aimed to evaluate the potential of the platelet-to-neutrophil ratio (PNR), as an early biomarker for clinically differentiating neonatal sepsis among pneumonia cases.
methodsWe performed a cross-sectional analysis of clinical and laboratory data collected from 1,103 patients with neonatal pneumonia [773 with pneumonia and 330 with pneumonia and sepsis (PS)].
resultsThe PS group had a lower PNR than the pneumonia group. Further analysis revealed that the incidence of PS was significantly higher in the low PNR group than in the high PNR group (43.9% vs. 15.9%,
conclusionsPNR can serve as an early biomarker for differentiating neonatal sepsis among pneumonia cases. Despite its potential, the PNR requires validation in multicenter studies.
