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
objectivesTo investigate the diagnostic performance of cerebrospinal fluid metagenomic next-generation sequencing (mNGS) for neonatal intracranial infections and its value in clinical decision-making.
methodsA retrospective observational study was conducted, enrolling neonates admitted to the Children's Hospital, Zhejiang University School of Medicine from 2020 to 2025 with suspected intracranial infection who underwent cerebrospinal fluid mNGS. The sensitivity of mNGS and its concordance with cerebrospinal fluid culture-quantitative polymerase chain reaction (qPCR) were calculated. Clinical impact was evaluated using predefined criteria, and samples were categorized accordingly into positive-impact and no-impact groups to explore independent factors influencing the positive impact of mNGS on clinical decision-making.
resultsAmong 61 neonates with suspected intracranial infection, 48 were confirmed. Pathogens were identified in 18 cases, of which 9 were detected exclusively by mNGS, accounting for 50% of etiological diagnoses. The sensitivity of mNGS was 31.3% (95%CI: 18.7%-46.3%), higher than that of cerebrospinal fluid culture-qPCR at 18.8% (95%CI: 8.9%-32.6%), though the difference was not statistically significant (
conclusionsCerebrospinal fluid mNGS provides positive support in etiological diagnosis and clinical decision-making for neonatal intracranial infection.
