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
backgroundReceipt of asthma specialty care reduces asthma morbidity in children, but children living in rural, socioeconomically disadvantaged, and remote areas face potential barriers to accessing specialists.
objectiveWe sought to evaluate the associations of rurality, Child Opportunity Index (COI), and distance with pediatric asthma specialist utilization among children with an indication for specialist referral.
methodsIn this retrospective cohort study using 2015-2021 Maine Health Data Organization All-Payer Claims Data, we identified children (<18 years old) with asthma and one of the following indications for specialist referral: a complicating comorbidity, higher-level controller medications, 3 or more courses of systemic corticosteroids within a year, or a respiratory hospitalization. We performed multivariate logistic regressions to calculate the adjusted associations between utilization of pediatric asthma specialists (physicians or advanced practice providers specializing in allergy/immunology or pediatric pulmonology) in the year after indication and children's rurality, COI, and driving time to specialists.
resultsAmong 12,014 children with indications for pediatric asthma specialist referral, 47% lived in micropolitan or rural areas, and 15% lived more than 1 hour from any specialist. A total of 2,296 children (19%) received care from specialists within a year of their indication. In adjusted analyses, children were significantly less likely to see specialists if they lived in small towns (adjusted odds ratio [aOR] 0.54, 95% CI 1.09-1.39) or isolated small rural areas (aOR 0.82, 95% CI 0.71-0.94), areas with a COI less than "very high" (for "very low," aOR 0.65, 95% CI 0.56-0.75), or farther from specialists (aOR 0.62 per hour, 95% CI 0.57-0.68).
conclusionsChildren in rural areas, in areas of low socioeconomic opportunity, and far from specialists are at an increased risk of not receiving indicated asthma specialist care.
