Health Systems and Self-Reported Medication Adherence in Patients with Hypertension: A cross-sectional comparison of Jamaica and Colombia.
Article in Research square, 2025. 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
Robust health care systems can support medication adherence as a strategy to improve blood pressure control in Latin America and the Caribbean. The Caribbean and South American Team Based Strategies to Control Hypertension (CATCH) study, conducted in Jamaica and Colombia, allowed us to examine how differing health systems (Jamaica - manual, paper-based, government run vs Colombia - electronic systems utilizing government contracted providers) influenced self-reported antihypertensive medication adherence among hypertensive patients. A total of 576 hypertensive patients from 14 primary care clinics completed telephone interviews between August 2021 and February 2022 during the COVID-19 pandemic. Self-reported medication adherence was measured using the IMPACTS-MAS questionnaire and patients categorized as having high (6), medium (5-5.5) or low (<5) adherence based on score. Country was used as a proxy for health systems in multivariable logistic regression models with medium/low adherence as the primary outcome. Jamaican patients were more likely to report medium/low adherence (49.3% vs 11.8% p <0.001). In Colombia, younger (< 60 years) and never married patients reported more medium/low adherence. Jamaican patients experienced longer wait times for services but were more likely to discuss medication changes with the pharmacist while Colombian patients had more discussions with their doctor. Jamaicans had a higher odds of medium/low adherence compared to Colombians (OR: 6.78 (95% CI: 3.91, 11.75) after adjusting for sociodemographic factors and health care experiences. Further exploration of health system issues that may explain these differences can inform strategies to improve medication adherence in the region.
