The Effects of Social Interaction Intervention on Cognitive Functions Among Older Adults Without Dementia: A Systematic Review and Meta-Analysis.
Review in Innovation in aging, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 and Objectives: Previous systemic reviews, predominantly including observational studies, have shown that participation in social activities is a protective factor against cognitive decline. However, this association is subject to potential reverse causality, creating a knowledge gap in our understanding of the effect of social interaction interventions on cognitive function. Therefore, this study aims to conduct a systematic review and meta-analysis of randomized controlled trials to examine the effects of social interaction interventions on cognitive decline among older adults without dementia. Research Design and Methods: This systematic review, registered in PROSPERO (CRD42022367828), systematically searched 6 databases from inception to May 6, 2022, to identify relevant articles on the effects of activities with social interaction components on cognitive function in community-dwelling older adults without dementia aged above 60. Two independent reviewers conducted study selection, data extraction, and bias assessment, with RevMan5.3 used for meta-analysis. Subgroup analysis was conducted to assess variation in intervention effects among subgroups. Results: We included 11 studies for qualitative analysis and 8 studies for the meta-analysis. The results showed that social interaction intervention had a significant effect on executive function (standardized mean difference [SMD] = 1.60; 95% CI, 0.50 to 2.70; Discussion and Implications: Social interaction interventions have a limited impact on cognitive function in older adults without dementia but showed potential effects on executive function. This finding offers insights for implementing social intervention in the community.
