Physical Activity and Systemic Biomarkers in Persons With COPD: Insights from a Web-Based Pedometer-Mediated Intervention.

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.

Abstract
Background: The relationships between physical activity (PA) and exercise performance and systemic biomarkers in persons with chronic obstructive pulmonary disease (COPD) have not been well characterized. The impact of PA promotion on biomarkers reflecting myocardial stress, systemic inflammation, and muscle injury is unclear. Methods: This secondary analysis used 3 previously published studies in persons with COPD (2 examined a PA intervention that promoted community-based walking for 3 months) to explore these relationships. PA (daily step counts) and exercise performance (6-minute walk test [6MWT]) were assessed. Serum N-terminal pro-β-type natriuretic peptide (NT-proBNP), the soluble receptor for advanced glycation end products (sRAGE), and muscle-type creatine kinase (CKMM) were assayed at baseline and 3 months. General linear models examined associations between PA/exercise performance and systemic biomarkers at baseline and the effect of the PA intervention on change in biomarkers. Results: Participants included 366 U.S. Veterans: 98% male, mean age 70±8 years, and forced expiratory volume in 1 second percentage predicted 59±21%. Lower baseline NT-proBNP, but not sRAGE or CKMM, was associated with higher daily step count (-0.95pg/ml per 1000 steps/day, Interpretation: Exercise performance is associated with NT-proBNP in persons with COPD. A 3-month community-based walking intervention is not associated with myocardial stress or muscle injury as assessed by NT-proBNP and CKMM, respectively. Clinical Trial Registration: NCT01772082 and NCT02099799.
