Impact of hypertension knowledge on adherence to antihypertensive therapy: a cross-sectional study in primary health care centers during the 2024 Sudan conflict.

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
backgroundHypertension is a global health issue, particularly in low- and middle-income countries. Effective management requires medication adherence, which is often compromised in conflict zones such as Sudan. This study examines the relationship between patients' knowledge of hypertension and their adherence to antihypertensive therapy in Sudan amidst ongoing conflict.
methodsA cross-sectional study conducted across six primary healthcare centers in Al-Dammer, Sudan, included 389 hypertensive patients selected through convenience sampling. Data were collected using face-to-face questionnaire that assessed sociodemographics, medication adherence (GMAS), and hypertension knowledge (HKT). Analyses were conducted in SPSS, with percentages for categorical data, means ± SD for continuous data, and nonparametric tests (Shapiro-Wilk, Kruskal-Wallis) for non-normal distributions.
resultsMost participants were female (63%), and 43.7% were over 60 years old. Knowledge levels were categorized as average (57.8%), high (25.2%), and low (17%). Adherence rates were as follows: 1% poor, 2.8% low, 22.6% partial, 26.5% good, and 47% high. A positive correlation was found between knowledge and adherence (r = 0.47, p < 0.001). Major barriers to adherence included affordability (43.4%) and unavailability of medications (36.2%). While 82.3% of participants had a history of controlled hypertension, only 58.4% remained controlled at their most recent measurement, with 41.6% presenting uncontrolled blood pressure, highlighting challenges in sustained hypertension management. Improved adherence was associated with higher income, better education, and controlled blood pressure.
conclusionHigher hypertension knowledge was significantly associated with better adherence and improved blood pressure control. However, sustained control remains a challenge, as 41.6% of participants had uncontrolled hypertension at their last measurement. Addressing economic barriers and medication shortages through targeted interventions is essential for improving long-term hypertension management in conflict settings.
