The current status and influencing factors of medication literacy among patients with cardiovascular diseases: a systematic review and meta-analysis.

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
Background: As an important domain of health literacy, medication literacy plays a critical role in ensuring the safe and effective use of medicines, especially among individuals with Cardiovascular Diseases (CVDs). Nevertheless, evidence regarding the overall level of medication literacy and the factors influencing it in this population remains limited. This study aimed to systematically evaluate medication literacy levels among patients with CVDs and to identify associated factors based on the Health Ecological Model (HEM). Methods: This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We systematically searched PubMed, Web of Science, the Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Wanfang Data, and the Vertically Integrated Projects database (VIP) for studies published in English or Chinese from database inception to 30 December 2025. Two reviewers independently performed study selection, quality assessment, data extraction, and analysis. Mean medication literacy scores and corresponding effect sizes were pooled using meta-analysis in Stata 18.0. Random-effects models were applied for all analyses due to substantial heterogeneity across studies. Heterogeneity was assessed using the I Results: A total of 34 studies involving 9,599 patients were included. Of these, 30 studies reported medication literacy levels. Given the substantial heterogeneity observed across all instrument subgroups, random-effects models were applied for pooling. The pooled mean scores were as follows: the Medication Literacy Questionnaire (MLQ): 4.56 [95% CI (4.36, 4.77), I Conclusion: Medication literacy among patients with CVDs remains suboptimal and is influenced by multidimensional factors. Individualized patient education, standardized counseling protocols, community-based services, and healthcare provider training are urgently needed. Multilevel interventions grounded in the HEM hold promise for improving medication use and informing policy development. Future large-scale, longitudinal studies employing standardized assessment tools are needed to elucidate causal relationships, underlying mechanisms, and sources of heterogeneity.
