Causal Relationship Between Physical Activity and Thymic Tumors Mediated by Circulating Cytokines: A Mendelian Randomization Mediation Analysis.

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
Physical activity reduces chronic disease risk and enhances immune function, but its causal relationship with thymic tumors-rare neoplasms of the anterior mediastinum-remains unclear. This study investigated whether physical activity reduces thymic tumor risk and whether circulating cytokines mediate this effect. We performed a two-sample Mendelian randomization (MR) analysis using genetic variants as instrumental variables for physical activity and cytokines. Data were obtained from large genome-wide association studies of Europeans, and included the following: physical activity (91,084 individuals), thymic tumors (473,681 individuals with 58 benign and 93 malignant cases), and cytokines (14,824 individuals). The inverse-variance weighted method served as the primary analysis. Genetically predicted physical activity was associated with reduced risks of benign (odds ratio [OR] = 0.381; 95% confidence interval [CI]: 0.158 to 0.921;
