Fluticasone- vs Budesonide-Based Dual Therapy for COPD.
Article in JAMA network open, 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
Importance: Inhaled corticosteroid (ICS)-long-acting β-agonist (LABA) inhalers are generally considered therapeutically equivalent when treating chronic obstructive pulmonary disease (COPD). However, metered-dose inhalers in the class are associated with substantially higher greenhouse gas emissions than dry powder formulations, and studies have raised questions about potential intraclass differences in clinical outcomes among patients receiving ICS-LABAs. Objective: To analyze COPD exacerbations and pneumonia hospitalizations associated with once-daily fluticasone furoate-vilanterol dry powder inhalers, twice-daily fluticasone propionate-salmeterol dry powder inhalers, and twice-daily budesonide-formoterol metered-dose inhalers in adults with COPD. Design, Setting, and Participants: This cohort study was conducted using longitudinal commercial claims data of US adults aged 40 years or older with COPD. Patients were 1:1 pairwise propensity score matched into 3 cohorts: (1) new users receiving fluticasone furoate-vilanterol vs budesonide-formoterol between January 1, 2014, and February 29, 2024; (2) new users receiving fluticasone furoate-vilanterol vs fluticasone propionate-salmeterol between January 1, 2014, and February 29, 2024; and (3) new users receiving fluticasone propionate-salmeterol vs budesonide-formoterol between January 1, 2007, and February 29, 2024. Exposures: Receipt of a once-daily fluticasone furoate-vilanterol dry powder inhaler (Breo Ellipta; GSK), twice-daily fluticasone propionate-salmeterol dry powder inhaler (Advair Diskus; GSK), or twice-daily budesonide-formoterol metered-dose inhaler (Symbicort; AstraZeneca). Main Outcomes and Measures: The primary outcomes were first moderate or severe COPD exacerbation and first pneumonia hospitalization. Hazard ratios and 95% CIs were estimated using Cox proportional hazards regression models. Results: The cohorts included 38 070 matched pairs of patients receiving fluticasone furoate-vilanterol vs budesonide-formoterol (58.8% women; mean [SD] age, 71.0 [9.0] years), 20 471 matched pairs of patients receiving fluticasone furoate-vilanterol vs fluticasone propionate-salmeterol (58.3% women; mean [SD] age, 69.9 [9.2] years), and 55 627 matched pairs of patients receiving fluticasone propionate-salmeterol vs budesonide-formoterol (56.2% women; mean [SD] age, 68.3 [9.0] years). Patients receiving fluticasone furoate-vilanterol had a 9% lower risk of moderate or severe COPD exacerbations compared with those receiving budesonide-formoterol (hazard ratio [HR], 0.91 [95% CI, 0.88-0.94]; number needed to treat [NNT] = 40) and a 6% lower risk compared with those receiving fluticasone propionate-salmeterol (HR, 0.94 [95% CI, 0.89-0.98]; NNT = 40). The risk of moderate or severe COPD exacerbation was similar for patients receiving fluticasone propionate-salmeterol and budesonide-formoterol (HR, 0.98 [95% CI, 0.95-1.01]). No differences were observed in the risk of pneumonia hospitalization across the 3 cohorts (fluticasone furoate-vilanterol vs budesonide-formoterol: HR, 1.03 [95% CI, 0.96-1.11]; fluticasone furoate-vilanterol vs fluticasone propionate-salmeterol: HR, 0.93 [95% CI, 0.85-1.03]; and fluticasone propionate-salmeterol vs budesonide-formoterol: HR, 1.04 [95% CI, 0.98-1.10]). Conclusions and Relevance: In this cohort study of new ICS-LABA users with COPD, once-daily dry powder fluticasone furoate-vilanterol inhalers were associated with slightly improved clinical outcomes compared with twice-daily metered-dose budesonide-formoterol inhalers and twice-daily dry powder fluticasone propionate-salmeterol inhalers. Further studies are needed to explore potential intraclass differences among inhalers used to treat COPD.
