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
objectiveInfluenza A virus (IAV) represents a significant etiological agent of respiratory infections in pediatric populations. The primary objective of this research was to evaluate the infection status and clinical manifestations associated with IAV in these pediatric patients.
methodsFrom April 2021 to December 2024, 10,310 pediatric inpatients diagnosed with respiratory infections were enrolled at Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital. Pathogen screening was systematically performed on biological specimens using targeted next-generation sequencing (tNGS) technologies.
resultsAmong 10,310 pediatric inpatients with respiratory infections screened by tNGS, 325 cases (3.2%) demonstrated IAV detection, predominantly distributed among preschool-aged children (3-5 years) and adolescents (5-11 years), with males predominating (male: female ratio 1.5:1). Monoinfection was observed in only 9 cases (2.8%), while 316 patients (97.2%) exhibited co-infections, primarily manifesting as IAV-bacterial-viral (97 cases, 29.8%) and IAV-bacterial (91 cases, 28.0%) co-infection patterns. Comprehensive pathogen profiling identified 41 distinct co-pathogens, with Haemophilus influenzae, Streptococcus pneumoniae, and Mycoplasma pneumoniae being the most common. Clinically, 33.2% developed respiratory complications (n = 108) and 41.2% extrapulmonary manifestations (n = 134), requiring median hospitalization of 6 days (IQR 5-8). Critical care needs included respiratory support in 20.6% (n = 67) and ICU admission in 4.6% (n = 15), underscoring the substantial disease burden associated with IAV co-infections in pediatric populations.
conclusionThis study delineates critical epidemiological and clinical patterns of pediatric IAV infections. A striking 97.2% of IAV-positive cases exhibited polymicrobial co-infections, necessitating implementation of comprehensive diagnostic panels. Clinically significant extrapulmonary complications developed in 41.2%, mandating vigilant multi-system monitoring beyond conventional respiratory surveillance. The 4.6% ICU admission rate, coupled with median hospitalization of 6 days (IQR 5-8), underscores the substantial healthcare burden imposed by IV-associated co-infections in pediatric populations.
