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: Diagnosing central nervous system infections (CNSI) in hematopoietic stem cell transplant (HSCT) recipients remains challenging due to nonspecific presentations and low sensitivity of conventional microbiological methods. Methods: This study evaluated the clinical utility of cerebrospinal fluid (CSF) metagenomic next-generation sequencing (mNGS) in 127 HSCT recipients (87 retrospective, 40 prospective) from Peking University People's Hospital. Pathogens detected by mNGS and conventional methods were validated via Sanger sequencing. Results: mNGS identified 20 pathogen-positive samples (19 confirmed by sequencing), while conventional methods detected none. mNGS demonstrated 82.6% sensitivity and 99.0% specificity for CNSI diagnosis, with sensitivity rising to 100.0% when combined with conventional approaches. Notably, mNGS excelled in detecting viral pathogens, particularly in allogeneic HSCT recipients. Conclusion: Our findings advocate for the integration of mNGS into the diagnostic algorithm for CNSI, especially in immunocompromised hosts. This approach enables earlier and more precise pathogen identification, which has the potential to streamline antimicrobial therapy and improve clinical management. To maximize its benefit and ensure reliable interpretation, mNGS results should be correlated with comprehensive clinical and paraclinical data. Further prospective studies are warranted to validate its impact on therapeutic decision-making and patient prognosis.
