Bridging Respiratory Exposures, Asthma, and Environmental Health in Corpus Christi (BREATHE-CC): a prospective cohort study protocol.
Article in BMC public health, 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
backgroundChildhood asthma disproportionately affects Hispanic children in the United States. Nevertheless, few longitudinal cohorts exist in Gulf Coast communities where environmental exposures may compound sociodemographic vulnerabilities. Corpus Christi, a majority-Hispanic city with high levels of petrochemical industrial operations, reports higher asthma prevalence than state and national averages. BREATHE-CC (Bridging Respiratory Exposures, Asthma, and Environmental Health in Corpus Christi) is a prospective cohort designed to investigate the role of air pollutants, household conditions, and social determinants of health in asthma exacerbations and wheezing phenotypes.
methodsApproximately 200 children less than 10 years of age with asthma will be enrolled from Driscoll Children's Hospital. Enrolled participants complete baseline assessments and are followed monthly for up to 18 months using a parent-reported modified ISAAC (International Study of Asthma and Allergies in Childhood) questionnaire that captures household exposures, asthma exacerbations, and wheezing episodes. Questionnaire responses will be validated and supplemented with electronic health record (EHR) reviews. Daily air pollutant concentrations (PM DISCUSSION: This is a longitudinal cohort examining Hispanic children residing in the Gulf Coast petrochemical corridor. In particular, the study integrates granular geospatial environmental monitoring to link daily air pollutant exposure levels with asthma exacerbation risk. GBTM will also be used to identify latent wheezing phenotypes, especially focusing on differences between infectious and non-infectious wheezing. Recruitment will occur at a single hospital in the Coastal Bend region with a modest sample size, which may limit generalizability. REGISTRATION: Clinical trial number: not applicable.
