The relationship between frailty, health literacy, and medication adherence in older adults.
Article 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
backgroundFrailty is a significant syndrome in aging, influenced by multiple factors. Timely identification of older adults at risk of frailty, along with appropriate interventions, can mitigate their adverse health consequences. This study examined the relationship between frailty, health literacy, and medication adherence among older adults.
methodThis cross-sectional study included 210 older adults (aged 60 and above) recruited from the Tabriz Education and Training Center for Retirees. Data were collected using the Tilburg Frailty Index (TFI), Test of Functional Health Literacy in Adults (TOFHLA), the Morisky, Green, and Levine (MGL) adherence scale, and a general information questionnaire. Data analysis was performed in SPSS v.27 using Spearman's correlation tests, independent t-tests, ANOVA, and logistic regression.
resultsThe mean age of the participants in this study was 68.92 ± 6.42. Of the participants, 125 (59.5%) were female and 85 (40.5%) were male, with 74.5% being married. Approximately 42% of the older adults were frail, and about 95% of them had high medication adherence. Also, 49.5% of the participants had sufficient health literacy. The findings of logistic regression analysis showed health literacy also had an apparent protective effect on frailty (OR = 0.024, P < 0.001), and an unhealthy lifestyle was significantly associated with frailty (OR = 51.896, P < 0.001).
conclusionThere is a relationship between unhealthy lifestyle, health literacy, and frailty in older adults. Health literacy may serve as an apparent protective factor against frailty. An unhealthy lifestyle could exacerbate frailty. Therefore, healthcare providers should focus on enhancing health literacy and a healthy lifestyle to prevent frailty in this population.
