The Child Opportunity Index as a Moderator of the Effectiveness of Multi-Modal Evidence-Based Asthma Care.
Article in Academic pediatrics, 2026. 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 evaluate if the Child Opportunity Index (COI) moderates associations between receiving a multimodal evidence-based asthma intervention and asthma-related emergency department (ED) reutilization among children.
methodsWe identified a prospective cohort of children ≤16 years old with ≥1 asthma-related ED visit(s) in 2022 from our city-wide asthma registry. We evaluated associations between receiving evidence-based asthma care through a locally validated intervention (exposure) and risk of ED reutilization within one year of the first ED visit (outcome) stratified by age (0-4, 5-11, 12-16 years), modeling recurrent events using survival analysis. We then tested for interactions between the COI and receiving the asthma intervention by stratifying by census tract COI 3.0 (moderator) which we dichotomized into lower (very low/low) and higher (moderate/high/very high) COI.
resultsThere were 4125 ED encounters among 2244 children. Most lived in lower COI areas (67.2%, n = 1507). Two-hundred and eighty children (12.5%) received the multimodal evidence-based asthma intervention, which overall was associated with a reduced risk of ED reutilization (adjusted hazard ratio [aHR] 0.58, 95%CI: 0.48, 0.71). Among children 5-11 years old, this reduction was significantly less in those from lower COI areas (aHR 0.64, 83.4%CI 0.52, 0.79) than in those from higher COI areas (aHR 0.21, 83.4%CI 0.12, 0.38) (p-interaction = 0.01). The COI did not moderate associations for other age groups.
conclusionsAdjusting effective evidence-based asthma care interventions to enhance their impact for children experiencing COI-related barriers, while partnering with communities to eradicate the root causes of lower COI, may be needed to achieve more equitable outcomes.
