Risk factors for recurrent attacks of wheeze in preschool children: a population-based cohort study in England.
Article in Archives of disease in childhood, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo determine factors associated with recurrent attacks of acute wheeze in preschool children.
designRetrospective cohort study.
settingEnglish primary electronic health data from the Clinical Practice Research Datalink linked with hospital data from Hospital Episode Statistics.
participants42 820 children aged 5 years or under with at least one acute wheeze presentation between 1 January 2013 and 31 December 2014. EXPOSURES: Demographic and clinical variables including age, sex, ethnicity, deprivation quintile, clinical comorbidities and previous asthma medication prescriptions and acute attacks were included in multivariable analyses.
main outcome measuresFurther healthcare presentation with an acute wheeze/asthma attack within 12 months.
resultsAlmost 40% (16 962/42 820) of children had a further attack within 12 months. The strongest predictors were hospitalisation with the index episode (RR 1.42; 95% CI 1.39 to 1.45) and an attack in the previous year (1.27; 1.22 to 1.32). Male sex (RR 1.06; 95% CI 1.03 to 1.08), South Asian ethnicity (1.08; 1.04 to 1.12), atopy (1.21; 1.18 to 1.24), prematurity (1.09; 1.04 to 1.14), increasing reliever prescriptions (1.04; 1.03 to 1.04), number of previous attacks (1.03; 1.02 to 1.04) and previous hospitalisation with wheeze (1.09; 1.05 to 1.14) were also associated with further attacks.Older age at presentation (RR 0.92; 0.91 to 0.93) and number of prescriptions for inhaled corticosteroids (0.96; 0.95 to 0.97) in the previous year were associated with lower risk for further attacks.
conclusionsOur findings can be used to aid clinical risk prediction for further attacks of wheeze in preschool children.
