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
Introduction: Effective asthma management depends on regular use of essential medications, yet high costs and low affordability often hinder adherence. This study assessed measured and perceived affordability of asthma medications, examined their associations with medication adherence, and identified factors associated with perceived affordability among patients in the Amhara Region, Ethiopia. Methods: An institution-based cross-sectional study was conducted from May to August 2024, including 312 eligible asthma patients attending four high-volume hospitals in the region. A total of 296 patients were consecutively sampled during the study period, utilizing structured interviewer administered questionnaires to collect data on socio-demographic, clinical, economic, and perceptions of medication affordability. Validity and reliability of the instruments were established through expert review, factor analysis, and Cronbach's alpha, ensuring accurate measurement of perceived affordability and adherence, with affordability assessed via income-based thresholds and medication adherence measured by the MARS scale. Analysis in SPSS involved descriptive statistics, Spearman's correlation, and multivariable logistic regression to explore relationships and predictors related to affordability and adherence. Results: Measured affordability was not significantly correlated with perceived affordability (ρ = -0.013, Conclusion: Perceived affordability, rather than measured affordability, significantly influences medication adherence among patients with asthma. Enhancing perceived affordability through expanded health insurance, consistent drug availability, reduced indirect costs, and promoting regular follow-up may improve treatment adherence and asthma outcomes by considering telemedicine, mobile health, or community-based follow-ups to cut transportation costs and save patients time.
