The association of oral health status and oral health-related quality of life with malnutrition, sarcopenia, and frailty in older adults.
Observational study in Irish journal of medical science, 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
backgroundThis study aimed to investigate the associations between oral health status and oral health-related quality of life (OHRQoL), malnutrition, sarcopenia risk, and frailty in individuals aged 65 years and older.
methodsIn this cross-sectional observational study, 101 older adults (59.4% male) who presented to a dental health center were evaluated. Oral health was assessed using the Decayed, Missing, and Filled Teeth (DMFT) index, and OHRQoL by the 14-item Oral Health Impact Profile (OHIP-14). Nutritional status, frailty, and sarcopenia risk were determined using the Mini Nutritional Assessment-Short Form (MNA-SF), Clinical Frailty Scale (CFS), and SARC-F, respectively.
resultsHigher OHIP-14 and DMFT scores were significantly associated with lower educational level, unmarried status, and infrequent dental visits. Both scores were higher in those with malnutrition risk (p = 0.002 and 0.029) and frailty (p = 0.008 and 0.006) compared to those without. OHIP-14 score also positively correlated with SARC-F score and negatively correlated with body weight (all p < 0.05). The ROC curve analysis identified the best cutoff values of OHIP-14 score as ≥ 14 for predicting malnutrition risk (AUC: 0.681) and as ≥ 18 for frailty (AUC: 0.655), and the cutoff level of DMFT score as ≥ 19 for frailty (AUC: 0.659).
conclusionThis study shows that oral health indicators might be significantly associated with malnutrition and sarcopenia risks, and frailty in older adults, underscoring the need to integrate oral health into comprehensive geriatric assessment and multidisciplinary care.
