Education-related inequality in overweight and obesity among Mongolian adults.
Article in PLOS global public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The increasing prevalence of overweight and obesity is a serious public health problem in low- and middle-income countries, closely linked to socioeconomic status, with significant disparities observed across different socioeconomic groups. However, the association between socioeconomic status and overweight or obesity has been less studied in Mongolia. The aim of this study was to examine socioeconomic inequality in overweight and obesity among adults in Mongolia. The data for this study was derived from the Mongolian National Tuberculosis Prevalence Survey, which included 41,777 participants aged 18 years and older. We used Erreyger's concentration index to assess the degree of socioeconomic inequality in overweight and obese individuals. Socioeconomic status was measured by educational level. A decomposition analysis was applied to identify the factors contributing to inequality in overweight and obesity among Mongolian adults. Among the study population, 33.4% were overweight, and 20.7% were obese. The Erreyger's concentration index for obesity was 0.059 (p < 0.01) among men and -0.047 (p < 0.01) among women. Furthermore, obesity was concentrated among the higher-educated men and lower-educated women. The decomposition analysis results show that education, employment status, and income were the main contributors to education-related inequalities in obesity for both men and women, except the age contribution. Education-related socioeconomic inequalities in overweight and obesity exist among Mongolian adults. Future national strategies for tackling obesity should address inequalities in the root social determinants.
