Case Report: Is it COPD? It is Fabry disease: a case in which bronchodilators were briefly used but not continued, prioritizing enzyme replacement therapy.

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
Background: Fabry disease, an X-linked lysosomal storage disorder, can present with mixed ventilatory dysfunction on pulmonary function testing. In patients with a smoking history, this finding may trigger a reflexive consideration of COPD and unnecessary bronchodilator use. We report a case where bronchodilators were briefly used following the diagnosis of Fabry disease, highlighting the clinical inertia that persists even after a definitive diagnosis. Case Presentation: A 39-year-old male with a 20-pack-year smoking history was diagnosed with Fabry disease through family cascade screening (α-galactosidase A activity: 4.93 nmol/L; plasma lyso-Gb3: 328.92 nmol/L; hemizygous GLA variant). Multisystem evaluation revealed mixed ventilatory dysfunction (FEV Conclusion: Even after Fabry disease is confirmed, the presence of a smoking history and abnormal spirometry can trigger reflexive bronchodilator use, illustrating powerful clinical inertia. Respiratory physicians should strictly adhere to COPD diagnostic criteria. Once Fabry disease is diagnosed, ERT should be prioritized as the disease-modifying therapy, and bronchodilators, if used at all, should be reserved for symptomatic patients as an adjunct, not a substitute.
