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
backgroundIn the digital age, the proliferation of information frequently leads to Cancer Information Overload (CIO) among breast cancer (BC) patients. CIO results in difficulties with decision-making and compromises patients' quality of life. Previous studies have primarily focused on the adverse outcomes of CIO, but research on its antecedents remains limited. Therefore, this study investigates the factors influencing CIO among BC patients.
methodsA single-center, cross-sectional study was conducted from February to August 2025. A convenience sampling method was employed to recruit 598 patients with BC from a tertiary traditional Chinese medicine (TCM) hospital in Guangdong Province. Participants completed a sociodemographic questionnaire, the Cancer Information Overload Scale (CIOS), the Digital Health Literacy Scale (DHLS), an asthenopia questionnaire, and the Depression, Anxiety, and Stress Scale (DASS-21). Data were analyzed using independent-samples t-tests, one-way analysis of variance, Pearson correlation analysis, and multiple linear regression analysis in SPSS.
resultsUnivariate analysis identified several significant influencing factors, including occupation, location, education level, caregiver, disease course, treatment, and comorbidities. Bivariate analysis revealed positive correlations between CIO and both asthenopia and depression. Multiple linear regression analysis further demonstrated that asthenopia, digital health literacy, education level, comorbidities, disease course, depression, and type of caregiver were significant predictors. Collectively, these variables explained 74.9% of the total variance in CIO.
conclusionCIO is highly prevalent among BC patients. Tailored intervention strategies based on the identified predictive factors are essential. These include optimizing health information delivery channels, incorporating multi-subject social resources, and delivering psychocognitive interventions. CLINICAL TRIAL NUMBER: Not applicable.
