Barriers to the Implementation of Iran's Clean Air Act: A Policy-Oriented Scoping Review.
Review in Environmental health insights, 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
Air pollution remains a serious environmental and public-health issue in Iran. Despite the Clean Air Act (CAA), enforcement is limited and compliance is weak. This 2025 scoping review outlines major barriers to CAA enforcement and proposes evidence-based policy actions. Multiple databases including Scopus, Web of Science, PubMed, and Google Scholar were searched and Policy documents, institutional reports, and legal texts were identified through Google and official organizational websites. Finally, a thematic analysis was conducted on the data using a four-dimensional conceptual framework. The data were categorized into four main categories of challenges. In the cultural, information and evidence domain, key issues included low policy priority for air pollution, weak public awareness, insufficient transparency, and lack of evidence for policymaking. Governance-related challenges involved institutional fragmentation, limited authority of the Department of Environment (DOE), multiple actors without coordination mechanisms, weak enforcement, and absence of performance metrics. Financial constraints included reliance on public budgets, lack of sustainable revenue sources, project interruptions due to budgetary constraints, and absence of cost-benefit models. Technical and infrastructural issues included lack of a data-governance system, absence of mandatory data and equipment standards, no technological roadmap, and weak industrial technology and monitoring infrastructure. Governance and institutional challenges represented the predominant share of factors hindering the CAA implementation in Iran. Addressing these challenges requires stronger political commitment, governance reform, sustainable financing, integrated data and monitoring systems, enhanced technical infrastructure, and evidence-based policymaking. A comprehensive, intersectoral, and long-term redesign of air-pollution control mechanisms in Iran is essential.
