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
Background: Frailty is highly prevalent among patients with chronic heart failure (CHF). Depressive symptoms and social support are significant psychosocial factors associated with frailty, yet how they interact to jointly relate to frailty remains insufficiently explored. Objective: This study aimed to investigate the interaction effect between depressive symptoms and social support on the presence of frailty in patients with CHF, to inform the development of targeted intervention strategies. Methods: A cross-sectional study was conducted among 380 patients with CHF from a tertiary hospital in Nanning, China. Data were collected using a general information questionnaire, the Patient Health Questionnaire-9 (PHQ-9), the Social Support Rating Scale (SSRS), and the FRAIL Scale. Logistic regression and interaction analyses were performed to evaluate correlations and interactions. Results: The prevalence of frailty was 41.3%. Logistic regression analysis identified depressive symptoms (odds ratio [OR] = 7.37, 95% confidence interval [CI]: 4.29-12.63) and low social support (OR = 5.88, 95% CI: 3.57-10.00) as associated factors for frailty (both Conclusion: Depressive symptoms and social support were significantly associated with frailty, and their interaction demonstrated a synergistic pattern. Longitudinal studies are warranted to explore the temporal nature of these associations. However, the single-center, regional, and male-predominant nature of the sample limits generalizability.
