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
Aim: Guided by the health ecology model, which posits that an individual's health is shaped by the dynamic interplay between personal and environmental factors, we investigated factors associated with depression in community-dwelling older adults with multimorbidity and developed a nomogram-based risk prediction model. While previous research has predominantly focused on depression in the context of single chronic diseases, the psychosocial and clinical complexities inherent to multimorbidity remain largely overlooked. This study addresses this gap by constructing a tailored prediction model that integrates the multidimensional determinants of depression in this vulnerable population. Methods: Using convenience sampling, a questionnaire survey was conducted among 679 older patients with chronic diseases from 12 community health institutions in China between March and August 2023. Participants were randomly divided into a training group ( Results: The prevalence rate of depression among older community residents with comorbid chronic conditions was 29.90%. We identified specific predictors for depression in this population: age ≥ 80 years, excess body weight, types of medication, self-management (the ability to actively manage one's health conditions), self-efficacy (confidence in one's ability to perform health-related actions), and educational level. For the training group, the area under the receiver operating characteristic (ROC) curve was 0.815, indicating a model accuracy of 74%, a sensitivity of 79%, and a specificity of 72%. Hosmer-Lemeshow fitting testing results in a χ Conclusion: Our new predictive model for the risk of depression in older patients in the community with multiple chronic diseases exhibited good discrimination, calibration and clinical practicability, serving as a valuable reference for the early detection of depression among this population.
