Differential Associations Between Religiosity and Cognition in the Korean Elderly With Alzheimer's Disease.
Article in Psychiatry investigation, 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
objectiveRecent studies have shown the beneficial effects of religiosity on the cognitive function of people with Alzheimer's disease (AD). We compared cognitive function among groups with different religious affiliations and investigated the relationship between religiosity and subdomains of cognitive function in patients with AD.
methodsWe recruited 247 patients with AD from psychiatric outpatient clinic. The Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was used to investigate different domains of cognitive function in patients with AD. Religiosity was measured using the Duke University Religion Index (DUREL), which assesses organizational religious activity (ORA), non-organizational religious activity (NORA), and intrinsic religiosity (IR). The cognitive functions of Christian, Buddhist, and religiously non-affiliated groups were compared. Additionally, hierarchical stepwise multiple regression was used to determine the relationship between ORA, NORA, and IR and the subdomains of cognitive function.
resultsThe Christian group showed better functioning in memory and constructional praxis than the religiously non-affiliated group after controlling for age, sex, and education, whereas the Buddhist group did not differ from the religiously non-affiliated group. ORA, NORA, and IR were significantly related to the Mini Mental Status Examination in the Korean version of CERAD (MMSE-KC), constructional praxis, and wordlist memory. In the multiple regression analysis, ORA showed positive relationships with constructional praxis and word-list memory, whereas NORA and IR were positively associated with MMSE-KC and word-list recall, respectively.
conclusionOur results suggest that the superiority in the cognitive functions of the Christian group may be associated with a high level of religious activities and IR that significantly influences memory and visuospatial ability in the elderly with AD.
