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: Stroke may bring psychological and cognitive challenges. Previous research revealed that several mediators, such as coping style and optimism, might be associated with cognitive impairment in patients with stroke. Objective: This study aims to establish a structural equation model of the relationships among optimism, coping style, and cognitive impairment, and to explore the mediating role of coping style in the association between optimism on cognitive impairment. Methods: Using a cross-sectional survey, 1,000 hospitalized patients with stroke from China were studied. The collected data were analyzed using correlation analyses, structural equation modeling, and regression analyses. SPSS 26.0 was used to construct logistic regression and decision tree models, and the area under the receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the two models. Structural equation modeling was used to examine the links among dispositional optimism, coping style, and cognitive impairment. The robustness of the model was verified using the bootstrap method. Results: The average scores of positive coping, negative coping, optimism, and cognitive impairment in patients with stroke were 19.26 ± 9.68, 10.49 ± 7.24, 23.22 ± 4.58, and 0.87 ± 1.69, respectively. The analysis of the receiver operating characteristic (ROC) curve showed that the predictive performance of logistic regression was slightly better than that of the decision tree model. SEM findings indicated that coping style serves as a significant mediator in the association between optimism and cognitive impairment. Conclusion: Both coping style and optimism were found to be significantly associated with cognitive impairment in patients with stroke, with coping style serving as a mediator of the association between optimism and cognitive impairment in this patient population. These cross-sectional findings suggest that, for inpatients with stroke, medical staff should consider paying attention to their cognitive function and assessing their psychological health status, such as their optimism and coping strategies, which may help inform the selection of supportive interventions that may benefit cognitive health.
