High prevalence and pathogen-specific variations of co-infections in pediatric adenovirus pneumonia: a retrospective epidemiological analysis from Northern China.
Article in Italian journal of pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundTo investigate the characteristics of co-infection pathogen profiles in children with adenovirus pneumonia and provide guidance for clinical diagnosis and rational treatment.
methodsA retrospective analysis was conducted on the etiological results of co-infections in children hospitalized with adenovirus pneumonia in the Respiratory Department of Hebei Children's Hospital from January 1, 2024, to December 31, 2024. Differences in co-infections across genders, age groups, and seasons were analyzed.
resultsAmong 5,373 children hospitalized with community-acquired pneumonia, 330 cases (6.1%) were diagnosed with adenovirus pneumonia, of which 310 (93.9%) exhibited co-infections. Bacterial co-infections predominated (70.0%, 231/330), with Streptococcus pneumoniae (45.2%), Haemophilus influenzae (40.9%), and Moraxella catarrhalis (2.7%) being among the most frequently detected, followed by Staphylococcus aureus (2.4%), Bordetella pertussis (2.1%), Pseudomonas aeruginosa, Enterobacter cloacae, and Streptococcus pyogenes. Viral co-infections were identified in 45.5% (150/330), primarily rhinovirus (26.4%), influenza A/B (7.3%), parainfluenza virus (5.8%), respiratory syncytial virus (RSV, 4.8%), metapneumovirus (4.5%), coronavirus (1.5%), and bocavirus (0.3%). Additionally, Mycoplasma pneumoniae co-infections accounted for 44.5% (147/330). Gender-specific analysis revealed significantly higher RSV co-infection rates in girls than boys (P < 0.05), with no notable gender disparities for other pathogens. Age-related differences showed higher bacterial co-infection rates in infants/toddlers compared to preschool/school-age groups (P < 0.05), where Streptococcus pneumoniae peaked in infants/toddlers, parainfluenza virus was most frequent in infants/toddlers, and Mycoplasma pneumoniae predominated in school-age children. Seasonally, co-infection rates remained consistent year-round, though RSV and influenza A/B peaked in winter, parainfluenza virus in summer, metapneumovirus was least detected in summer, and Mycoplasma pneumoniae exhibited the highest positivity in autumn and the lowest in spring.
conclusionAdenovirus pneumonia in children in this region exhibits a high rate of co-infections, predominantly bacterial (especially Streptococcus pneumoniae and Haemophilus influenzae), followed by viral (rhinovirus, influenza, parainfluenza, RSV) and Mycoplasma pneumoniae. Co-infection profiles vary by gender, age, and season. Timely identification of co-pathogens is critical for guiding rational antimicrobial use and improving prognosis.
