Vitamin A deficiency in the MENA region: a 30-year analysis (1990-2019).
Article in Frontiers in nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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: Vitamin A deficiency (VAD) is a common micronutrient deficiency that imposes a substantial burden worldwide. This study examined the burden of VAD from 1990 to 2019 in the Middle East and North Africa (MENA) region by age, sex and sociodemographic index (SDI). Methods: The data were obtained from the Global Burden of Disease (GBD) 2019 database. We reported the prevalence, incidence, and years lived with disability (YLDs) that were attributable to VAD for the MENA region, along with its constituent countries. Results: In 2019, the MENA region had 30.6 million prevalent cases of VAD, with an age-standardized prevalence rate of 5249.9 per 100,000 population. In addition, VAD was responsible for 62.2 thousand YLDs, with an age-standardized YLD rate of 10.2 per 100,000. The age-standardized prevalence [50.3% (-55.9 to -44.7)] and YLD [-49.3% (-55.3 to -43.1)] rates of VAD have significantly decreased since 1990. In 2019, the MENA region's VAD-attributable YLD rate was below the global average for males and females across all age groups. Additionally, SDI was negatively associated the age-standardized YLD rate of VAD. Conclusion: This study underscores the necessity of frequently updating health data and developing guidelines and regulations to prevent, detect early, and effectively treat VAD in the MENA countries.
