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

purposeThe purpose of this study was to compare research definitions of childhood asthma based on parent-reported data.

methodsWe conducted a multicenter, prospective cohort study of 921 infants hospitalized for bronchiolitis. Follow-up was conducted via biannual parent interviews. Asthma definitions were developed using parent-reported data: clinician diagnosis by the age of 5 years ("broad definition"), clinician diagnosis by the age of 5 years with either asthma medication use or asthma symptoms during the age of 4-4.9 years ("epidemiologic definition"), clinician diagnosis by the age of 5 years with either long-term inhaled corticosteroid use or asthma symptoms during the age of 4-4.9 years ("strict definition"), and a "flexible definition" met by any two of the three criteria in the epidemiologic definition. Asthma outcome definitions were evaluated using unadjusted associations with known major asthma risk factors and validated against the medical record in a subset (n = 116).

resultsAsthma prevalence for the broad definition was 294 of 875 (34%); epidemiologic definition, 235 of 859 (27%); strict definition, 229 of 859 (27%); and flexible definition, 364 of 826 (44%). Risk factors had similarly strong associations with definitions that required clinician diagnosis and weaker associations with the flexible definition. The epidemiologic and strict definitions had the highest specificity (96%) and positive predictive value (92%).

conclusionsThe parent report of clinician-diagnosed asthma correlates well with known asthma risk factors.
