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
Objectives: Lower respiratory tract infections (LRTIs), including bronchitis and pneumonia, are common pediatric conditions. Accurate and timely pathogen identification is essential in this population, with targeted next-generation sequencing (tNGS) significantly improving detection rates. This study aimed to systematically assess the clinical utility of tNGS in identifying pathogens in pediatric LRTIs. Methods: A retrospective analysis of 107 pediatric patients with lower respiratory tract infections (LRTIs) was conducted between January 2024 and December 2024. The concordance of tNGS, quantitative polymerase chain reaction (qPCR), and microbial culture results with clinical diagnoses was assessed. Data were analyzed using the Statistical Package for the Social Sciences (SPSS), with statistical significance set at Results: Of the 107 pediatric patients, 34 (31.8%) had single-pathogen infections while 73 (68.2%) had multiple infections, with bacterial-viral co-infections comprising 42.5% of the latter group. The tNGS results demonstrated a concordance rate of over 66% with clinical diagnoses, which was significantly higher (P < 0.001) than that of qPCR and culture. The analysis revealed 80% concordance between tNGS and qPCR results. Notably, tNGS demonstrated 90% concordance with culture methods in approximately 70% of comparative detections. Furthermore, for Conclusion: The tNGS results demonstrated high concordance with the clinical diagnosis, supporting its high applicability in diagnosing pathogens in pediatric patients with severe, mixed, or refractory infections.
