The effectiveness of a cognitive behavioural therapy for insomnia based intervention to improve sleep quality in nursing home residents, a cluster randomised controlled trial.
Trial report in European geriatric medicine, 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
purposeTo evaluate the effectiveness of a structured, team-delivered intervention based on cognitive behavioural therapy for insomnia (CBT-I) on sleep and related outcomes in nursing home residents.
methodsA cluster randomised controlled trial with intervention group and control group was conducted in five nursing homes between February 2024 and February 2025. A total of 240 residents were included, with a mean age of 86.8 years and 72.5% being female. Sleep outcomes were assessed using the Pittsburgh Sleep Quality Index (PSQI) for residents who were cognitively intact or mildly impaired, and the Neuropsychiatric Inventory-Nursing Home version (NPI-NH) for residents with significant cognitive or language impairments.
resultsIn the PSQI group (n = 124) there was a significant interaction effect between time and group for the total PSQI score (p = 0.031). No significant between-group difference was observed at follow-up. In the NPI-NH group (n = 116), no significant effect was found for sleep and nighttime behaviour disturbances (p = 0.061). However, residents in the intervention group showed significant improvements across several neuropsychiatric domains, including reductions in delusions, agitation/aggression, depression, disinhibition and aberrant motor behaviour.
conclusionAlthough the intervention did not result in significant between-group differences in sleep outcomes, these findings suggest that a structured, team-delivered CBT-I-based intervention may contribute to improvements in behavioural and psychological symptoms of dementia (BPSD). This underscores the often-overlooked relationship between sleep and BPSD and supports further investigation of team-based sleep interventions in long-term care settings.
