Updated analysis of the pharmacogenomics of pediatric bronchodilator response.
Article in Pharmacogenetics and genomics, 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
This short communication serves as an update to previously published pilot study results on bronchodilator response (BDR) in children with asthma. We expanded our cohort from 54 to 165 pediatric patients seeking emergency department care for an asthma exacerbation. We obtained measured BDR before and after albuterol administration using the Pediatric Asthma Severity Score and collected genomic DNA. Based on a literature review, we analyzed whether 21 candidate single-nucleotide polymorphisms (SNPs) were associated with BDR. Among the three SNPs initially reported in our pilot study as significantly associated with BDR (rs912142, rs7081864, and rs7903366), we confirmed that rs7081864 was still significantly associated with suboptimal BDR (odds ratio, 0.47; confidence interval, 0.24-0.92). If externally validated in broader studies, simple outpatient testing for that SNP variant could help guide pharmacologic therapy for acute asthma symptoms.
