Understanding visual impairment trends in the Gulf Council Countries: An analysis from 1990 to 2021 and time-series predictions for 2030.
Article in PloS one, 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
backgroundThis research investigates blindness prevalence trends in Gulf Cooperation Council (GCC) countries from 1990 to 2021 and provides projections up to 2030. The study aimed to inform public health planning, policy formulation, and healthcare delivery in the region.
methodsUsing data from the Global Burden of Disease Study 2021, we conducted a time-series analysis applying AutoRegressive Integrated Moving Average (ARIMA) models to evaluate age-standardized prevalence rates and Disability-Adjusted Life Years (DALYs) for blindness. Country-specific and gender-specific were analyzed. Forecasts for 2022-2030 were generated and validated against observed data.
resultsBetween 1990 and 2021, most GCC countries exhibited declining trends in blindness prevalence. Bahrain's rate decreased from 13,498.2 to 12,884.7 per 100,000, Kuwait from 12,873.8 to 12,881.4, Saudi Arabia from 14,207.2 to 14,166.8, and the UAE from 11,905.9 to 11,869.6. Oman and Qatar showed relative stability with minor fluctuations. Gender disparities were consistent, with higher prevalence among females in all countries except the UAE. DALYs also declined across the region, with Saudi Arabia reporting the highest burden. Forecasts for 2022-2030 indicate continued reductions in most countries, though Oman may experience a moderate increase.
conclusionsThe findings underscore the need for targeted public health strategies, improved healthcare infrastructure, and gender-sensitive interventions to address visual impairment in the GCC. Continuous monitoring and international collaboration are essential to sustain progress and mitigate future burdens.
