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

Objectives: The aim of this study was to compare spirometric parameters between recreational male marathon runners (MR) and a control group (CG) representative of the male population of the Pomerania region to assess the association between endurance training and pulmonary function. Methods: A total of 31 amateur MR and 82 men in the CG aged 35-66 years participated in this study. The CG represented the male population of the Pomerania region (Poland). The analysis included basic spirometric parameters: forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), Tiffeneau index (FEV1/FVC), and the potential confounding factors: body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), smoking status, and history of obstructive lung diseases. Results: Recreational MR demonstrated significantly higher FVC and FEV1 values than the CG, both in absolute values and as percentages of predicted values ( Conclusions: Recreational male MR demonstrated significantly higher FVC and FEV1 values than controls from the general male population. No significant differences were observed in the prevalence of obstructive airway disorders. Because of the relatively small sample size and cross-sectional design, the findings should be interpreted with caution. Further longitudinal studies are needed to better clarify the relationship between endurance training and pulmonary function.
