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
aimThis study examines whether expressed emotion (EE) mediates the association between caregiver relationship closeness and behavioural and psychological symptoms of dementia (BPSD).
methodsWe recruited 64 families with dementia in Osaka and collected data for 3 months. Caregiver-patient relationship closeness was assessed using the Relationship Closeness Scale (RCS), and BPSD was measured with the Neuropsychiatric Inventory Questionnaire (NPI-Q). EE was evaluated using the Family Attitude Scale (FAS).
resultsThe results indicated significant correlations between EE, relationship closeness, and BPSD, showing that higher caregiver intimacy levels were associated with lower aggression in dementia people. Mediation analysis revealed that EE significantly and mainly mediated the relationship between RCS and BPSD.
conclusionsThe findings underscore the importance of interventions focused on improving caregiver-patient relationships and managing caregiver emotional expressions to mitigate BPSD. These insights are valuable for developing targeted support programs for dementia care.
