Investigating predictive factors of participation in colorectal cancer screening based on the Preventive Health Model (PHM) and health literacy.

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
backgroundColorectal cancer is a leading cause of cancer-related morbidity globally. Early detection through screening can markedly reduce mortality; however, participation remains suboptimal across diverse populations, including Iran. Understanding predictors of screening behaviour is essential to inform effective interventions. This study investigates predictors of colorectal cancer screening participation, framed by the Preventive Health Model (PHM) with health literacy as a key construct.
methodsA cross-sectional survey was administered to employees aged 40 and older at a university. Participants completed validated instruments measuring PHM constructs and health literacy. Data were analysed with SPSS using multivariate regression to identify independent predictors of screening uptake.
resultsHigher levels of self-efficacy (p = 0.001, ß=0.44), perceived susceptibility (p = 0.002, ß=0.32), intention (p = 0.006, ß=0.27), and social support (p = 0.009, ß=0.22) were all significantly associated with participation in colorectal cancer screening, with self-efficacy being the strongest predictor. Conversely, there were no significant relationships found between cancer worries (p = 0.09, ß=-0.08), response efficacy (p = 0.40, ß=0.04), health literacy (p = 0.09, ß=0.08), and colorectal cancer screening.
conclusionsHealth literacy supports comprehension but self-efficacy and social support more strongly predict screening participation. Interventions should prioritize boosting self-efficacy and fostering supportive environments to enhance uptake.
