Pathogen spectrum identified by targeted nanopore sequencing and exploratory analysis of hematological biomarkers in suspected intracranial infections.

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
Background: Intracranial infections are severe, life-threatening conditions often caused by diverse pathogens. Targeted nanopore sequencing (TNPseq) offers rapid and accurate pathogen identification, addressing the limitations of traditional diagnostic methods. Besides the pathogen types, factors like inflammation levels also affect treatment outcomes. Thus, we combined TNPseq with clinical indicators to characterize pathogen-specific host-response heterogeneity and optimize clinical stratification in infected patients. Methods: This retrospective study included 255 patients with suspected intracranial infections, among whom 39 with complete clinical and hematological data were analyzed. Pathogen detection was conducted using TNPseq, and the consistency of pathogen distributions between the full and screened cohorts was evaluated. The diagnostic performance of C-reactive protein (CRP), neutrophil ratio (NR), and procalcitonin (PCT) was assessed via logistic regression and receiver operating characteristic (ROC) curve analysis. Mediation analysis was used to explore the relationship between CRP, NR, and the length of hospital stay (LOS). Results: The most common pathogens identified were Conclusion: TNPseq effectively identifies a broad range of pathogens in intracranial infections. CRP and NR serve as critical indicators of inflammatory burden and host-response heterogeneity, aiding in risk stratification and personalized management when integrated with TNPseq.
