Person-centered non-pharmacological interventions for agitation in dementia: a meta-analysis with subgroup analysis by behavioral subtypes.

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
Objective: This meta-analysis aimed to evaluate the overall efficacy of person-centered non-pharmacological interventions for agitation in dementia and to compare treatment effects across behavioral subtypes, specifically physical aggressive agitation, physical non-aggressive agitation, and verbal agitation. Methods: A systematic literature search was conducted in PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) from database inception to March 2026. Randomized controlled trials (RCTs) evaluating person-centered non-pharmacological interventions for agitation in individuals with dementia were included. The primary outcome was agitation, with subgroup analyses performed for behavioral subtypes. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using random-effects models. Risk of bias was assessed using the Cochrane RoB 2.0 tool. Results: Six RCTs were included. Person-centered non-pharmacological interventions significantly reduced overall agitation compared with control conditions (SMD = -0.48, 95% CI: -0.84 to -0.13, Conclusion: Person-centered non-pharmacological interventions significantly reduce overall agitation in individuals with dementia, with the most consistent effects observed for verbal agitation. The lack of significant effects on physical agitation subtypes, coupled with substantial heterogeneity, highlights the critical need for further research and intervention development specifically targeting these physical behaviors. These findings support the use of personalized interventions as a first-line strategy, particularly for verbal symptoms, while emphasizing the importance of further research to optimize interventions for physical agitation.
