Oral mucosal lesions and oral health-related quality of life (GOHAI) in nursing home residents and community-dwelling older adults in Türkiye: a comparative cross-sectional study.
Observational study in BMC geriatrics, 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
backgroundTo compare the prevalence of oral mucosal lesions and oral health-related quality of life between nursing home residents (NHR) and community-dwelling older adults (CDA) in Türkiye.
methodsThis observational cross-sectional study included 639 individuals aged ≥ 65 years: 329 NHR from seven state-authorized nursing homes and 310 CDA attending a university dental clinic between July 2024 and January 2025. Demographics, systemic conditions, denture use, and dental visit history were recorded. Oral mucosal lesions were identified through standardized examinations by a blinded oral medicine specialist. Oral health-related quality of life was assessed using the validated Turkish version of the Geriatric Oral Health Assessment Index (GOHAI-TR). Group comparisons employed Chi-squared, Fisher’s exact, and Mann–Whitney U tests (p < 0.05).
resultsNHR had higher denture use (p = 0.001) and more Alzheimer’s and cerebrovascular disease, whereas CDA had more ischemic heart disease, smoking, and xerostomia (p < 0.05). Candidiasis and angular cheilitis were more common in NHR, while oral lichen planus, ulcerative lesions, and fissured tongue predominated in CDA. Red–blue lesions, particularly sublingual varicosities, were more frequent in CDA (41.6% vs. 31.6%, p = 0.009). CDA had higher GOHAI functional limitation scores (p = 0.001), indicating better self-perceived oral function, while NHR scored higher in pain/discomfort (p = 0.006). No significant differences were observed in psychological impact or total GOHAI scores.
conclusionNHR exhibited greater functional limitations and higher rates of infectious oral diseases. Personalized oral care strategies, including specialist-led assessments, targeted infection prevention, and structured caregiver training, are needed in long-term care to preserve oral function and quality of life in older adults.
