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
Purpose: This study examined the association between physical activity and internet addiction among college students and tested the indirect associations of interoceptive awareness and emotion regulation difficulties using a serial mediation model. Methods: A cross-sectional online survey was conducted among 677 Chinese college students. Standardized instruments were used to assess physical activity, interoceptive awareness, emotion regulation difficulties, and internet addiction. Descriptive statistics, correlation analyses, one-way analysis of variance (ANOVA), and serial mediation analyses were performed using SPSS 27.0 and Mplus 8.3. Indirect associations and their confidence intervals were estimated using 5,000 bootstrap resamples. Continuous and nonlinear PA specifications, alternative scoring, and measurement checks were added. Results: Participants were categorized into low-, moderate-, and high-level physical activity groups. High physical activity, relative to low physical activity, had a negative conditional direct association with internet addiction scores (β = -0.200, Conclusion: In this cross-sectional study of college students, physical activity was negatively associated with internet addiction, but indirect associations involving the intermediary scores were specification-dependent and limited by measurement weaknesses. While consistent with embodied cognition theory, these findings preclude causal inference regarding directionality, mechanisms, or intervention effects. The results should therefore be interpreted as observational and hypothesis-generating. Longitudinal and experimental studies are needed to clarify temporal and causal relationships.
