Urban-rural differences in pneumonia risk in patients with chronic obstructive pulmonary disease: a nationwide register-based study.
Article in European clinical respiratory journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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: Urban-rural differences in treatment within chronic obstructive pulmonary disease (COPD) have been documented in Denmark, and we aim to investigate such differences in the risk of pneumonia. Methods: A Danish register-based cross-sectional study including patients with an International Classification of Diseases 10 Results: Patients outside capital municipalities had significantly increased risk of experiencing outpatient pneumonia (Metropolitan: Odds ratio (OR) = 1.32, 95% confidence interval (CI): 1.25-1.39. Provincial: OR = 1.26, 95% CI: 1.21-1.31. Commuter: OR = 1.25, 95% CI: 1.20-1.31. Rural: OR = 1.28, 95% CI: 1.23-1.33). No significant differences were found for pneumonia hospitalization. Conclusions: Compared to patients in capital municipalities, patients with a hospital-registered COPD diagnosis in non-capital municipalities had a higher risk of annually redeeming at least one prescription for antibiotics typically used for outpatient pneumonia. We were unable to detect differences in pneumonia hospitalization between municipality types. Our study was not designed to assess causality, and we stress the need for future research to provide actionable insights for health policy makers.
