Cardiovascular Outcomes Among Patients with COPD Prescribed with LABA or LAMA: A Real-World Territory Wide Study.
Article in Advances in therapy, 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
introductionThis study aims to compare cardiovascular outcomes among patients who received long-acting beta-agonist (LABA) and long-acting muscarinic antagonist (LAMA) and thereby better inform the choice of pharmacotherapy prescription for patients with chronic obstructive pulmonary disease (COPD).
methodA real-world territory-wide retrospective cohort study using electronic data patient databases in Hong Kong was conducted. Patients with COPD without cardiovascular disease who were new users of LABA or LAMA from public hospitals in Hong Kong between 2010 and 2019 were identified and were followed up for 3 years after treatment initiation. Incidences of cardiovascular events were compared. Propensity score matching was employed to match important patient characteristics and clinical features.
resultsAfter the propensity score matching, 5020 patients were included: 2510 treated with LABA and 2510 with LAMA. At 3-year follow-up, 19.6% of patients experienced cardiovascular events. LAMA treatment was associated with a higher incidence of cardiovascular events compared to LABA (20.2% vs 19.0%, adjusted hazard ratio [aHR] 1.14, p = 0.04). This difference was primarily driven by increased risks of new-onset atrial fibrillation (7.93% vs 6.53%, aHR 1.30, p = 0.01). Incidence rates were similar between groups for ventricular tachycardia and fibrillation (0.52% vs 0.80%, p = 0.32), acute coronary syndrome (4.06% vs 3.82%, p = 0.33), ischemic stroke (2.39% vs 2.59%, p = 0.98), and heart failure hospitalization (10.8% vs 9.84%, p = 0.05).
conclusionPatients with COPD treated with LAMA might have higher incidence of atrial fibrillation when compared with LABA but not other cardiovascular events.
