Association of Participation in the Collaborative Care Team With Behavioral and Psychological Symptoms of Dementia and Caregiver Distress.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe management of behavioral and psychological symptoms associated with dementia (BPSD) was challenging for the physicians and their caregivers, which placing a great burden on their caregivers, families, and communities. Our study aimed to explored the factors associated with changes in BPSD severity and caregiver distress.
methodsThis retrospective cohort study examined 738 community-dwelling individuals who were newly diagnosed with dementia and had BPSD at baseline. Participants were categorized based on a case manager-centered collaborative model that evaluated unmet needs and offered appropriate interventions to patients and caregivers. A generalized linear model with backward selection identified factors linked to changes in total NPI and NPI Distress scores one year after diagnosis.
resultsParticipants dismissed during follow-up (compared with those with continuous follow-up, β = 3.2, 95% CI = 0.83-5.5, p = 0.008) and participants cared for by a sole informal caregiver (compared with ADL-independent participants whose caregivers only provide companionship, β = 3.9, 95% CI = 1.2-6.7, p = 0.006) were significantly associated with higher NPI total scores. Male sex (β = -3.0, 95% CI = -4.9, -1.0, p = 0.003), and using assistive devices and home modifications (β = -3.0, 95% CI = -6.0, -0.01, p = 0.05) were protective factors. Similar patterns emerged for caregiver distress, with follow-up discontinuation (β = 1.7, 95% CI = 0.18, 3.2, p = 0.029), using respite care (β = 4.4, 95% CI = 0.00, 8.7, p = 0.05), and participants cared by a sole informal caregiver (β = 2.7, 95% CI = 0.95, 4.4, p = 0.003) increasing distress.
conclusionsThe case manager-centered dementia collaborative care model was associated with reduced short-term BPSD severity and caregiver distress, with sex, care mode, and social resource use as predictive factors. Integrating collaborative care models in long-term care healthcare systems is recommended to better support dementia patients and caregivers.
