1 · What the graph read from it

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.

2 · The registry

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

backgroundBronchiolitis, due to respiratory syncytial virus, is the most common cause of hospitalization and lower respiratory tract infections in infants and toddlers across the globe. Data on RSV epidemiology in Romania are limited and are mainly derived from national surveillance systems. Understanding regional trends in RSV bronchiolitis, its etiology, and its severity is important while assessing the potential impacts of future prevention measures.

methodsWe conducted a retrospective cohort study including infants hospitalized with bronchiolitis between 2019 and 2023 in a tertiary pediatric center in Central Romania. Demographic, clinical, and treatment data were analyzed. Comparative analyses between RSV-positive and RSV-negative cases were performed among patients tested for RSV. Disease severity was assessed using oxygen saturation at admission and length of hospital stay.

resultsA total of 2967 bronchiolitis hospitalizations were identified during the study period. After exclusion of 167 cases due to hospitalization <24 h or incomplete medical records, 2800 patients were included in the final analysis. The number of admissions decreased in 2020 (

conclusionsRSV infection was associated with a more severe clinical course in our cohort and continues to play a central role in the burden of disease. The variability observed in treatment practices also suggests that further efforts are needed to better align clinical management with current evidence-based recommendations.
