Socioeconomic development, longevity and prevalence of obesity and overweight: The retrospective longitudinal analysis of international data.
Article in Dialogues in 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
Objectives: Due to the economic growth at the end of the 20th century, people in low-income countries live longer but still spend most of their income on food. These countries, as well as affluent countries, demonstrate a rising prevalence of obesity. The interplay of longevity and obesity at different levels of economic development is not clear. Methods: We used World Bank, International Monetary Fund, and Global Burden of Disease data on population size, longevity, prevalence of obesity, and income. Results: After stratifying countries by income, we found a long-term increase in life expectancy with an increase in the prevalence of obesity in countries of all income levels. In the countries of the richest quintile, the increase in longevity is not associated with a further increase in the prevalence of obesity. Conclusions: The economic growth everywhere leads to an increase in the length of life and is associated with an increase in obesity prevalence. In poor countries, where access to food is limited and customs of consumption differ, socioeconomic development is associated with an increase in longevity and a large increase in prevalence of obesity. It may be the cause of the slower progress in life expectancy in the future.
