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
Objectives: Asthma exacerbations pose substantial risk to adolescents. We evaluated whether documented nicotine use, cannabis use, or concurrent use is associated with increased emergency department (ED) management intensity and adverse short-term outcomes during asthma exacerbations. Methods: Using the TriNetX database, we identified adolescents aged 11 to 21 years presenting to the ED with an acute asthma exacerbation from January 1, 2015, to January 1, 2025. Patients were categorized into nicotine-only, cannabis-only, or concurrent nicotine-cannabis cohorts based on documented International Classification of Diseases, 10th Revision (ICD-10) codes and matched to controls without such diagnoses. Outcomes were reported as risk ratios (RRs) with 95% CIs during 0 to 1-day and 1- to 30-day intervals. Results: After matching, cohorts included 4604 nicotine-only, 2679 cannabis-only, and 1045 co-use patients. During their ED encounter, co-use patients demonstrated the strongest associations with acute respiratory failure (RR, 4.63; 95% CI, 2.71-7.89), hospital admission (RR, 2.47; 95% CI, 1.80-3.38), and critical care services (RR, 1.92; 95% CI, 1.19-3.09). Nicotine-only and cannabis-only cohorts also showed increased pharmacologic escalation and diagnostic testing. Between 1 and 30 days, co-use patients had higher rates of repeat exacerbation (RR, 1.72; 95% CI, 1.36-2.17), ED revisits (RR, 1.54; 95% CI, 1.29-1.85), pneumonia (RR, 2.20; 95% CI, 1.05-4.62), and critical care use (RR, 2.07; 95% CI, 1.10-3.90); nicotine-only and cannabis-only cohorts additionally demonstrated this association to a lesser degree. Conclusion: Adolescents with documented nicotine or cannabis use, especially concurrent use, experience more intensive ED management and worse short-term outcomes during asthma exacerbations, supporting consideration of targeted acute care pathways.
