Using the medication adherence reasons scale (MAR-scale) to identify the reasons for non-adherence in Chinese hypertensive patients.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis study aimed to determine the prevalence of medication non-adherence and to explore the factors influencing it among Chinese hypertensive patients. PATIENTS AND
methodsA total of 571 hypertensive patients hospitalized in a tertiary hospital in Xi'an, China were invited to participate in this cross-sectional study. The Chinese Version of Medication Adherence Reasons Scale (ChMAR-Scale) was used to identify the most common reasons for non-adherence to hypertension medications.Binary logistic regression analysis was employed to analyze independent risk factors for adherence in hypertensive patients.Descriptive statistics were used to calculate the adherence rates and trends in the reasons for non-adherence.
resultsApproximately 66.9% of the patients did not adhere to their medications.Age (adjusted odds ratio [AOR] = 0.976, 95%CI:0.955-0.998, P = 0.032),education level(AOR = 0.566, 95% CI:0.419-0.765,P < 0.001) and blood pressure (BP) categories (AOR = 0.580, 95% CI: 0.439-0.767,P < 0.001) were independently associated with hypertensive medication adherence. Belief issues and self-perception issues were identified as the main reasons for medication non-adherence.These included self-adjustment of medications according to BP or physical condition, checking whether the medicine was still needed, concerns about long-term effects, and the belief that there was no longer a need to take the medicine.
conclusionPoor medication adherence is widespread among Chinese hypertension patients. More attention should be paid,and effective strategies should be developed to address the factors affecting treatment adherence.These factors include certain sociodemographic factors,such as age,education level and BP categories as well as belief issues and self-perception issues of hypertensive patients. The findings of this study can potentially assist healthcare providers in formulating targeted interventions to improve medication adherence.
