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

Objective: While prior studies showed lower socioeconomic status was associated with worse acute asthma exacerbations (AAE) and asthma-related emergency department/urgent care (ED/UC) visits, few have quantified contributions of risk factors. We aim to identify and quantify risk factors driving these disparities across levels of neighborhood deprivation. Methods: We conducted a cohort study of 79,562 adults with mild asthma in Kaiser Permanente Southern California, United States, during 2013-2018, with follow-up through 2019, comparing participants in Neighborhood Deprivation Index (NDI) quintiles five (Q5, most deprived) and one (Q1, least deprived). Outcomes included AAE and asthma-related ED/UC visits. We employed Oaxaca-Blinder decomposition to quantify contributions of 14 risk factors to these disparities. Results: Individuals in NDI Q5 had a 1.5% higher rate of AAE and a 3% higher rate of ED/UC visits than those in Q1. The 14 risk factors explained 61.2% of the AAE disparity and 52.3% of the ED/UC disparity. Race and ethnicity contributed most, 33.1% of the AAE disparity and 22.8% of the ED/UC disparity, followed by body mass index, prior asthma exacerbations, and exercise levels. Conclusions: These results underscore the need for targeted interventions addressing socioeconomic and behavioral factors to reduce asthma-related health disparities, particularly in disadvantaged populations.
