Association of health literacy, medication beliefs, and illness perception among older adults with hypertension: a community-based study.
Article in BMC public health, 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
backgroundHealth literacy, medication beliefs, and illness perception significantly influence self-care among older adults patients with hypertension. However, the relationship between these factors has not been precisely established in this population. This study aimed to examine the associations of health literacy with medication beliefs and illness perception among older adults with hypertension.
methodsThis cross-sectional study was conducted among 475 hypertensive older adults in Khorramabad City, Iran. Participants were selected using a multistage random sampling method. Data were collected using demographic information questionnaire, the Health Literacy for Iranian Adults (HELIA) questionnaire, Beliefs about medicines questionnaire (BMQ), and Brief Illness Perception Questionnaire (BIPQ). Data were analyzed using SPSS 23 software, by independent t-tests, analysis of variance, Pearson correlation coefficient, and regression analysis. A p-value less than 0.05 was considered significant.
resultsThe mean scores (with standard deviations) for health literacy, medication beliefs, and illness perception among the older adults were 57.82 (17.32), 75.14 (6.02), and 38.36 (8.89), respectively. The findings indicated a significant positive correlation between health literacy (overall and across all dimensions) and necessity, overall benefit, and necessity-concern subtraction score (P < 0.001). Conversely, a significant negative correlation was found between health literacy (overall and all dimensions) and concern, overall loss, overall misuse, and illness perception. The regression analysis identified a significant positive relationship between necessity-concern and health literacy (P < 0.001). However, the relationship between illness perception and health literacy was inverse and non-significant (P = 0.158).
conclusionThe findings indicate that many older individuals face challenges with health literacy, which is closely tied to their perceptions of diseases and beliefs about medications. Therefore, in addition to developing educational programs to improve health literacy, it is crucial to address and correct negative beliefs about medications and perceptions of diseases.
