Healthcare efficiency across GCC countries: an exploratory DEA study.
Article in Frontiers in public health, 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: Healthcare systems in the Gulf Cooperation Council (GCC) countries have expanded substantially in recent decades, accompanied by increasing healthcare expenditures. However, higher spending does not necessarily translate into proportionally better population health outcomes, highlighting the importance of evaluating healthcare expenditure efficiency. Objective: This exploratory study assessed the relative efficiency of healthcare expenditure across GCC countries using Data Envelopment Analysis (DEA). Methods: An exploratory cross-sectional comparative analysis was conducted across six GCC countries: Saudi Arabia, United Arab Emirates, Qatar, Kuwait, Bahrain, and Oman. Health expenditure per capita, expressed in purchasing power parity (PPP)-adjusted current international USD, was used as the input variable, while life expectancy at birth was used as the output variable. Data were obtained from the World Bank World Development Indicators and World Health Organization databases. An input-oriented variable returns to scale (VRS) DEA model was applied. Sensitivity analyses were conducted using alternative DEA specifications, including constant returns to scale (CRS), input-oriented, and output-oriented models. Results: Relative healthcare expenditure efficiency varied across GCC countries. Qatar and Oman were positioned on the efficiency frontier under the primary VRS model, whereas Bahrain and Kuwait showed relatively high efficiency scores. The United Arab Emirates and Saudi Arabia demonstrated comparatively lower scores. Sensitivity analyses produced broadly consistent findings. However, the results should be interpreted cautiously because of the exploratory design, limited number of decision-making units, and dependence of DEA estimates on model specification. DEA efficiency scores represent relative efficiency within the selected framework and should not be interpreted as direct measures of healthcare quality or overall health system performance. Conclusion: Healthcare expenditure efficiency varied across GCC countries, suggesting that higher spending does not consistently correspond to better population health outcomes. These preliminary findings emphasize the importance of effective resource utilization. Future research using larger datasets, longitudinal designs, and broader health system indicators is needed.
