The association between rural/urban residence status and patient-reported outcomes in individuals with Chronic Obstructive Pulmonary Disease (COPD): Protocol for a systematic review and meta-analysis.
Article in PloS one, 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
introductionRural residency is associated with a disproportionate burden of chronic obstructive pulmonary disease (COPD) and poorer COPD health outcomes. While increasing focus has been placed on the influence of rural/urban residence on clinical outcomes, little is known about the impact of rural versus urban residency status on patient-reported outcome measures (PROMs) in individuals with COPD, despite the use of PROMs to tailor interventions and treatments to individual patient needs.
objectiveThe objective of this review is to synthesize evidence of a relation between rural/urban residency status and PROMs in individuals with COPD.
methodsBeginning May 2025, we will search EBSCO, Elsevier, Cochrane Library, PubMed, and relevant websites to identify research published between January 1, 2012, and November 1, 2024. Two reviewers will independently screen titles, abstracts, and full texts, with a third reviewer to resolve any discrepancies. All data sources and selection management will be fulfilled and housed in the Covidence systematic review software. The primary outcome of this review is the association between rural/urban residency and PROMs in individuals with COPD. If appropriate, a meta-analysis will be conducted. Sub-group analysis will be performed by sex. Sensitivity analysis will be performed by excluding studies with "low quality" based on risk of bias assessment. ETHICS AND DISSEMINATION: This study is exempt from institutional review as it will be a secondary analysis of published data. Results of this study are expected by September 2025 and will be disseminated in a relevant peer-reviewed journal.
