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: Dementia is a significant global health challenge, with many cases in China, causing heavy socioeconomic burden. Current treatments mainly relieve symptoms, but lifestyle interventions may reduce dementia risk. However, existing research on the association between lifestyle factors and cognitive outcomes in older adults with cognitive impairment in China lacks regional specificity, which limits the development of tailored intervention strategies for diverse local elderly populations. Objective: The present study aimed to assess the impact of specific lifestyle factors, including smoking status, physical activity levels, and smartphone utilization patterns, on cognitive function and among individuals diagnosed with dementia. Methods: One hundred and sixty-nine community-dwelling individuals diagnosed with dementia according to DSM-5 criteria were recruited for this study. Lifestyle Questionnaire was collected, the Mini-Mental State Examination (MMSE) was used to measure the cognitive function and the quality of life (QoL) scale was used to assess the quality of life. The relationship between lifestyle and cognitive function and quality of life was analyzed by simple and multiple linear regression models. Results: Univariate analysis revealed that smoking, moderate aerobic exercise and smartphone use were positively correlated with MMSE score. However, in multivariate models, the significant association with smoking status was no longer observed, while the positive association with ≤1 hour of daily aerobic exercise remained statistically significant. Additionally, anaerobic exercise and smartphone use exceeding 1 hour per day were independently and positively associated with QoL, whereas smoking showed an independent negative association. Alcohol consumption did not demonstrate a statistically significant association with QoL, despite a positive trend observed in some preliminary models. Conclusion: Moderate aerobic/anaerobic exercise and smart device use are promising non-drug interventions for cognition and QoL in dementia. Smoking's link to worse QoL highlights the need for targeted cessation.
