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: Demoralization describes a state of existential distress, isolation, impotence, hopelessness, helplessness, and loss of purpose and meaning in life. Demoralization is associated with suicidal thoughts, which could lead to a desire for hastened death. Perceived stress could be viewed as the sense of imbalance between the stressors experienced by an individual in daily life and his or her coping capability. Many studies have tested the relationships between perceived stress, sleep disturbance, and demoralization; however, the mechanism of sleep disturbance has not been fully evaluated. Objective: To verify the relationship between perceived stress and demoralization and explore the mediating effect of sleep disturbance on the relationship between perceived stress and demoralization in hemodialysis patients. Materials and methods: A cross-sectional questionnaire survey using convenience sampling from July to August 2022, 547 hemodialysis patients from ten hospitals filled out the Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI), Demoralization Scale (DS), and general information questionnaire. The data were analyzed using SPSS 26.0, and path analysis and structural equation modeling were used to explore the relationships among perceived stress, sleep disturbance, and demoralization. Results: Perceived stress was significantly and positively associated with demoralization ( Conclusion: Perceived stress affects demoralization among hemodialysis patients, and sleep disturbance is a mediator in the relationship. Perceived stress in hemodialysis patients should be measured and effectively managed to improve positive effects on demoralization. It is necessary for medical staff to consider implementing perceived stress interventions with an emphasis on construction of sleep strategies to assist hemodialysis patients improve their demoralization.
