Path analysis of biopsychosocial correlates of physical activity among patients with colorectal cancer.
Article in Scientific reports, 2025. 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
This study explored the underlying pathways linking physical activity (PA) and associated factors among Chinese patients with colorectal cancer (CRC) using path analysis. Although the benefits of PA in cancer care are well established, participation rates among CRC patients in China remain unclear, and influencing pathways are not fully understood. A cross-sectional survey was conducted with 211 inpatients at a tertiary cancer hospital in Southwest China from January to June 2024. Data on PA levels, fatigue, anxiety, depression, perceived exercise barriers and benefits, social support, and exercise self-efficacy were collected. The hypothesized model was tested using Mplus version 8.3. The median PA level was 3066 MET-min/week (i.e., metabolic equivalent minutes per week; IQR: 1584-4914), with 56.87% meeting the American College of Sports Medicine's guidelines. The model showed good fit: χ2/df = 1.418, CFI = 0.988, TLI = 0.974, RMSEA = 0.045, and SRMR = 0.021. Fatigue, perceived barriers, and exercise self-efficacy showed direct associations with PA, whereas anxiety, depression, and perceived benefits related indirectly via self-efficacy and/or social support. Our path analysis disentangles direct vs indirect links, pinpoints self-efficacy as the key modifiable target, and highlights fatigue and perceived barriers as priority levers-informing multidimensional, targeted interventions.
