Polypharmacy among Saudi seniors in Hail region: A cross-sectional study on prevalence and association with medication adherence.
Observational study in Medicine, 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
Polypharmacy, defined as the concurrent use of 5 or more medications, is prevalent among the older adults, particularly those with multiple chronic conditions. This study assesses the prevalence of polypharmacy among older adult patients in the Hail region of Saudi Arabia and explores its association with medication adherence. A cross-sectional study was conducted, involving 247 older adult patients (aged 60 and above) from an outpatient pharmacy in Hail between August and December 2023. Medication adherence was evaluated using the Simple Medication Adherence Questionnaire. Statistical analyses, including chi-square tests, were performed to assess the relationship between polypharmacy and adherence levels. The mean age of participants was 71.83 years, with females accounting for 51.4%. The study found that 52% of participants were engaged in polypharmacy, with hypertension (70.9%) and diabetes (60.3%) being the most prevalent chronic illnesses. A significant association was found between polypharmacy and medication adherence; 63.4% of individuals taking 5 or more medications reported nonadherence, compared to 36.6% among those taking fewer than 5 (χ² = 20.448, P < .001). Overall, 57.5% of participants demonstrated suboptimal adherence. The findings underscore the high prevalence of polypharmacy and its adverse effect on medication adherence among older adults in Hail. The significant association between the number of medications and adherence levels emphasizes the importance of targeted interventions, including educational programs and caregiver support, to enhance health outcomes in this vulnerable population.
