1 · What the graph read from 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.

2 · The registry

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: Chronic obstructive pulmonary disease (COPD) is a major public health concern globally, and physical activity is considered a modifiable factor in its prevention. Purpose: This study examined the association between daily step count, step frequency, and the prevalence of chronic obstructive pulmonary disease (COPD) using nationally representative data. Patients and Methods: A cross-sectional analysis was conducted using data from adults aged ≥40 years in the 2003-2006 National Health and Nutrition Examination Survey (NHANES). Participants wore accelerometers for 7 days to measure daily step count and three step frequency indicators: bout cadence, peak 30-minute cadence, and peak 1-minute cadence (steps/minute). Weighted logistic regression was used to assess associations with COPD, adjusting for demographic, behavioral, and health-related covariates. Sensitivity analyses and subgroup analyses were conducted to confirm robustness. Results: Among 3690 participants (representing ~26.8 million US adults), higher daily step count and step frequency were inversely associated with COPD prevalence. Compared to those taking <4000 steps/day, those taking ≥8000 steps/day had a 63% lower odds of COPD (OR 0.37, 95% CI 0.15-0.91; P for trend <0.001). Higher bout cadence (92.3-153.4 steps/minute) and peak 30-minute cadence (69.8-128.2 steps/minute) were also associated with significantly reduced COPD odds (ORs 0.30 and 0.33, respectively). Combined higher step count and frequency yielded a greater risk reduction. Restricted cubic splines indicated a nonlinear association, and ROC analysis showed moderate discriminatory power (AUC 0.71-0.75). Results remained robust in sensitivity analyses and across subgroups. Conclusion: In this cross-sectional study of US adults, higher daily step counts and greater walking cadence were associated with a lower prevalence of COPD. These findings support the relevance of step-based metrics in assessing COPD risk, although longitudinal studies are needed to establish causality.
