Overcoming barriers and enhancing strategies in organ transplantation systems: a systematic review.
Review in Frontiers in transplantation, 2026. 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
Background: Organ transplantation is one of the major achievements of modern medicine, yet the global shortage of organs remains a serious challenge. This shortage increases mortality among patients on waiting lists. Although up to 80% of people support organ donation, far fewer register as donors, creating a clear "knowledge-action gap." Aim: This systematic review aimed to identify key barriers to organ donation and evaluate strategies to improve donation rates. Methods: A systematic search was conducted across PubMed, Scopus, Web of Science, and Google Scholar for peer-reviewed studies published in the last decade. Following PRISMA guidelines, 33 studies were included, covering randomized controlled trials, cross-sectional, and mixed-methods designs. Study quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Tools. Results: Barriers to organ donation were found to be complex and interconnected, involving social, psychological, and systemic factors. Lack of knowledge was the most common issue, with up to 91% reporting poor awareness and only 11% aware of relevant laws. Sociocultural and religious concerns also influenced decisions, with 38.8% reporting misconceptions and 58% lacking family support. Psychological barriers were significant, with 69% fearing health complications and expressing mistrust in the healthcare system. At the system level, despite general willingness, only 37.3% of healthcare professionals had donor cards. However, targeted interventions showed positive outcomes. Educational programs increased willingness to register from 12% to 68% and improved knowledge from 36.4% to 88.5%. Conclusion: The main barrier to organ donation is the gap between willingness and action, largely due to uncertainty and lack of understanding. Bridging this gap requires a combined approach: providing simple, culturally appropriate education about donation and improving healthcare systems to build trust and reduce financial and practical burdens on donors.
