Exploring underlying factors associated with effective coverage of diabetes care in Iran: a systems thinking approach.
Article in BMC health services research, 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
backgroundThe prevalence of diabetes has been increasing in Iran; yet, effective glycemic control remains suboptimal. This study aimed to identify the underlying root causes that influence the effective coverage of diabetes care in Isfahan Province, Iran.
methodsWe conducted a qualitative study based on face-to-face semi-structured interviews with twenty-nine participants, including fourteen health workers and fifteen patients with diabetes within primary healthcare (PHC) facilities in Isfahan Province, Iran. We conducted a thematic analysis and then mapped causal relationships through a causal loop diagram and characterized system archetypes, such as limits to growth and shifting the burden archetypes.
resultsWe identified four themes, namely, integrated, accessible, team-based, and continuous care capacities for diabetes management, along with their corresponding facilitators and barriers. Perceived facilitators such as the implementation of standard clinical guidelines like the IraPEN, the availability of electronic information systems such as the Integrated Primary Health Care System, known as SIB, the supply of essential medications and medical equipment, basic health insurance coverage, and screening, detection, and treatment adherence by healthcare workers, all improve the coverage of diabetes care. In contrast, perceived barriers such as weak infrastructure, poor coordination across healthcare providers and between levels of care, pharmaceutical expenditures, healthcare worker shortages, task diversification and workload, time constraints of healthcare workers, and inadequate patient engagement limit effective coverage.
conclusionsDespite efforts to integrate diabetes care into the PHC context and the expansion of basic health insurance coverage, underlying constraints such as fragmented care delivery, limited accessibility, and insufficient team-based and poor continuous care continue to impede the effective coverage of diabetes care in Iran. Our findings suggest that strengthening infrastructure for integrated care within the PHC setting, enhancing financial protection for patients, particularly those with complications, recruiting adequately trained healthcare workers for diabetes care, and promoting patient engagement are essential for providing effective diabetes management.
