Cardiorespiratory fitness in working adults undergoing rehabilitation: the role of lifestyle and body composition- a cross-sectional study.
Article in Frontiers in physiology, 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
Introduction: Cardiorespiratory fitness (CRF) is one of the most important predictors of mortality and morbidity. Lifestyle changes concerning diet, sleep, physical activity (PA), and substance use have a systemic impact and can prevent 80% of premature deaths and chronic diseases. CRF, being a parameter dependent on the functioning of all systems, may therefore be affected by changes in lifestyle. Aim: To examine the relationship between declared lifestyle (eating habits, alcohol use, smoking, sleep, weekly PA and body composition) and CRF. Methods: A sleep questionnaire based on Polish version of the Athens Insomnia Scale, dietary and substance survey from the PaLS study and a PA survey based on the IPAQ-SF were conducted. Body composition was assessed using a bioelectrical impedance analysis device, with particular focus on body fat percentage and skeletal muscle mass. The Åstrand-Rhyming fitness test was used to estimate VO Results: Self-reported weekly PA was positively correlated with estimated VO Conclusions: Self-reported weekly PA, longer sleep duration, and favorable body composition (lower body fat percentage, higher skeletal muscle mass percentage) were associated with higher VO
