Clinical characteristics and prognostic differences of children with acute bronchitis across different age groups.

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
Objective: This study aimed to analyze the clinical characteristics of children with acute bronchitis in different age groups and to identify the risk factors for the development of chronic cough in these children. Methods: Clinical data of 290 children hospitalized for acute bronchitis at Linquan County People's Hospital from August 2022 to September 2024 were retrospectively collected. The children were categorized into three age groups: <1 year, ≥1 year and <3 years, and ≥3 years. Data collected included gender, age, home address, gestational age, birth weight, parental smoking status, symptoms such as stuffy nose, sputum, fever, peak temperature, fever duration, hospitalization duration, anemia, white blood cell count (WBC), C-reactive protein, neutrophils (Neu), and lymphocytes. The children were further divided into a good prognosis group ( Results: Significant differences were observed among age groups in WBC and Neu levels and in the proportions of children with stuffy nose, sputum, and fever. Among the 290 children, 34 (11.7%) developed chronic cough. In multivariable logistic regression analysis, gestational age (adjusted OR [aOR], 0.385; 95% CI, 0.263-0.563), parental smoking (aOR, 2.479; 95% CI, 1.104-5.569), and anemia (aOR, 4.734; 95% CI, 1.539-14.563) were independently associated with chronic cough. The nomogram showed good discrimination, with an AUC of 0.819 (95% CI, 0.735-0.903). Conclusion: The clinical characteristics and symptoms of children with acute bronchitis differ by age. Gestational age, parental smoking, and anemia were independently associated with chronic cough following acute bronchitis. The nomogram may help identify children at higher risk of chronic cough, although external validation is warranted.
