1 · What the graph read from it

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.

2 · The registry

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

objectiveTo evaluate the diagnostic utility of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and leukocyte count in detecting ventriculitis among adult and pediatric patients with traumatic brain injury (TBI) who underwent external ventricular drain (EVD) placement.

methodsWe performed a retrospective cohort study using the TriNetX Global Collaborative Network. Patients with TBI who underwent EVD placement were stratified by age (≥18 years vs. <18 years) and presence of ventriculitis. Propensity score matching was used to balance demographic and clinical characteristics between cohorts. Laboratory values, including ESR, CRP, leukocyte count, cerebrospinal fluid (CSF) glucose, procalcitonin, and CSF lactate, were compared using median and interquartile range (IQR) as provided by the TriNetX platform.

resultsIn adults, leukocyte count, CRP, and ESR demonstrated overlapping distributions between cohorts and did not reliably distinguish ventriculitis. Although CRP reached statistical significance, values showed substantial variability and limited clinical interpretability. In the pediatric cohort, CRP, leukocyte count, and procalcitonin similarly demonstrated overlapping distributions without consistent differentiation between groups. In contrast, CSF glucose was consistently lower in patients with ventriculitis across both adult and pediatric populations. CSF lactate was higher in the adult ventriculitis cohort; however, this finding was based on a limited subset of patients and should be interpreted with caution.

conclusionSystemic inflammatory markers, including CRP, ESR, and leukocyte count, demonstrated limited diagnostic utility for distinguishing ventriculitis in TBI patients with EVDs. CSF-based markers, particularly CSF glucose, were more consistently associated with ventriculitis, while CSF lactate may have a potential adjunctive role. These findings support prioritizing CSF analysis and pathogen-specific testing for accurate diagnosis. Future studies should focus on prospective validation and the development of more specific biomarkers.
