Associations Between Physical Activity and Preserved Ratio Impaired Spirometry: A Cross-Sectional NHANES Study.
Article in International journal of chronic obstructive pulmonary disease, 2024. 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
Background: Preserved ratio impaired spirometry (PRISm) is considered to be one of the early chronic obstructive pulmonary disease states, and there are few studies on PRISm prevention. We aimed to evaluate the relationship between physical activity and the risk of PRISm. Methods: A cross-sectional study was conducted using data from US adults who participated in the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2012. We examined the association between physical activity and PRISm using multivariable logistic regression models and a restricted cubic spline (RCS) model. Results: Compared to the normal and chronic obstructive pulmonary disease (COPD) groups, the PRISm group had lower levels of physical activity (3537.2 MET-min/week in the normal group vs 3452.1 MET-min/week in the COPD group vs 2841.5 MET-min/week in the PRISm group). Adjusted multivariable regression models revealed that greater physical activity dose (more than 4800 MET-min/week) was associated with lower odds of PRISm (adjusted odds ratio [aOR] = 0.77, 95% confidence interval [95% CI] = 0.61-0.98; Conclusion: A greater total physical activity level was associated with a lower risk of PRISm in US adults, especially in populations with a BMI ≥ 25 kg/m
