Self-Care Behaviors and Dietary Habits Among Patients with Heart Failure: A Cross-Sectional Study.

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
backgroundSelf-care and healthy dietary habits are fundamental components of heart failure (HF) management, yet the relationship between dietary quality and self-care remains insufficiently explored. This study investigated the association between dietary habits and self-care behaviors among patients with HF.
methodsA cross-sectional study was conducted among 137 adults with HF attending outpatient clinics in Greece. Self-care behaviors were assessed using the Hippocratic Heart Failure Self-Care Scale (HHFSCS), and dietary quality was evaluated using the validated Greek version of the Cardiovascular Diet Questionnaire-2 (CDQ-2). Associations between demographic characteristics, dietary measures, and self-care were examined using non-parametric tests and multivariable general linear models adjusted for demographic characteristics.
resultsThe mean HHFSCS score was 41.0 ± 11.3, indicating a moderate level of self-care. Higher scores were observed for medication adherence and appointment keeping, whereas lower scores were observed for exercise, smoking-related behaviors, alcohol-related behaviors, and symptom monitoring. The mean total CDQ-2 score was 8.57 ± 7.17. Overall dietary quality was not significantly associated with total self-care after adjustment for age, sex, marital status, educational level, and employment status (B = -0.102, 95% CI: -0.338 to 0.134,
conclusionsOverall dietary quality was not significantly associated with total self-care in this sample of patients with HF. However, the observed association between the SFA component and self-care suggests that specific aspects of dietary behavior may warrant further investigation. Given the cross-sectional design and reliance on self-reported measures, these findings should be interpreted cautiously and do not establish directionality or causality. Prospective studies incorporating objective dietary and behavioral measures are needed to further clarify the relationship between dietary habits and self-care in HF.
