G20 Country Burden of High BMI-Related Liver Cancer: Trends from 1990 to 2021 and Projections to 2050.
Article in Journal of epidemiology and global 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
backgroundLiver cancer associated with a high body mass index (BMI) poses a significant global health challenge, particularly within G20 nations characterized by elevated rates of Hepatitis B and C infections. This study aims to quantify the burden of liver cancer attributable to high BMI across G20 countries by employing the Global Burden of Disease (GBD) 2021 data and advanced statistical modeling techniques, assessing key metrics such as disability-adjusted life years (DALYs), deaths, years of life lost (YLLs) and years lived with disability (YLDs) from 1990 to 2021, segmented by gender and age.
methodsThe burden of liver cancer attributable to high BMI was assessed using GBD 2021 data and advanced statistical modeling techniques. Estimates for DALYs, deaths, YLLs, and YLDs were generated and analyzed by gender and age.
resultsThe results indicate a concerning increase in liver cancer burden, particularly in nations with high to high-middle socio-demographic indices, where Saudi Arabia exhibited the highest liver cancer rates linked to Hepatitis B and C. Alarmingly, individuals aged 60–69 experienced significantly elevated age-standardized rates of DALYs, deaths, YLDs, and YLLs, revealing a differential impact based on both age and underlying viral infections. Projections for 2022 to 2050 further signal an unsettling rise in liver cancer cases and mortality rates associated with high BMI, highlighting the urgent need for targeted public health initiatives.
conclusionsIt is imperative that future health policies prioritize international collaboration, increase healthcare investments, and address obesity-related lifestyle factors in order to mitigate the impending health crisis posed by high BMI-associated liver cancer across G20 countries.
