Initial treatment of COPD with LABA-ICS or LABA-LAMA: real-world comparative effectiveness.
Article in BMJ open respiratory research, 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
backgroundThe 2023 Global initiative for chronic Obstructive Lung Disease (GOLD) recommendations advocate long-acting beta RESEARCH QUESTION: What is the comparative effectiveness of initiating COPD treatment with LABA-ICS versus LABA-LAMA inhalers, particularly in patients with multiple COPD exacerbations, in a real-world clinical practice setting? STUDY DESIGN AND
methodsWe identified a cohort of patients with COPD, 40 years of age or older, from the United Kingdom's Clinical Practice Research Datalink. Treatment-naïve initiators of single-inhaler LABA-ICS or LABA-LAMA, with no prior asthma, LABA, LAMA or ICS use, were compared on the incidence of moderate or severe COPD exacerbation over 1 year, after adjustment by propensity score weighting.
resultsThe study cohort included 20 750 initiators of LABA-ICS inhalers and 16 594 of LABA-LAMA. The overall adjusted HR of a first moderate or severe exacerbation with LABA-ICS relative to LABA-LAMA was 1.03 (95% CI 0.98 to 1.08). Among patients with two or more prior exacerbations, the HR of exacerbation with LABA-ICS versus LABA-LAMA was 0.89 (95% CI 0.81 to 0.97), while it was 1.07 (95% CI 1.00 to 1.15) among patients with no prior exacerbations. The HR was 0.92 (95% CI 0.86 to 0.99) among those with forced expiratory volume in 1 s (FEV
interpretationIn a real-world clinical practice setting of COPD treatment, initiating therapy with LABA-ICS inhalers may be more effective than LABA-LAMA inhalers among patients with multiple exacerbations, particularly those with FEV
