Prevalence of adherence and its impact on quality of life in oral anticoagulant users in Egypt: A cross-sectional study from two Egyptian university hospitals.

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
backgroundOral anticoagulant therapy (OAT) is critical for managing thromboembolic disorders, but adherence challenges significantly impact its effectiveness and patients' quality of life (QoL). This study explores the predictors of adherence and their effects on QoL among OAT users in Egypt.
methodsThis multi-center cross-sectional descriptive study with an analytical component was conducted at Mansoura University Hospital and Ain Shams University Hospital. Participants were adults over 18 years old, on OAT for at least one month, who provided informed consent. Convenience sampling was used to recruit 212 participants. Data were collected using a survey that included socio-demographic details, the Arabic Version of the Adherence to Refills and Medications Scale (ARMS), and the WHOQOL-BREF questionnaire. Statistical analyses included descriptive statistics, chi-square tests, Student's t-tests, and multivariate logistic regression.
resultsThe study included 212 participants, with an average age of 55 years, 57% female and 43% male. Among the participants, 25.5% were adherent to their anticoagulant regimen, while 74.5% were non-adherent. Adherence was significantly higher among NOAC users (44.4%) compared to warfarin users (19.0%). Key predictors of adherence included the use of NOACs (OR = 2.7), residency in rural areas (OR = 2.4), and having first-degree relatives in medical specialties (OR = 2.4). Quality of life scores were significantly higher for NOAC users in psychological, social, and environmental domains compared to warfarin users. The overall QoL score was also higher in NOAC users. Poorer adherence was associated with lower scores in these QoL domains.
conclusionsOur study indicates that NOACs enhance adherence and quality of life relative to VKAs. Key adherence predictors include NOAC use, rural residency, and having relatives in medical professions. Educational level, initially significant, did not persist as a predictor in multivariate analysis. Targeted strategies are needed to improve adherence and patient outcomes.
