Obesity Fact Sheet in Korea, 2020: Prevalence of Obesity by Obesity Class from 2009 to 2018.
Article in Journal of obesity & metabolic syndrome, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05869799 (Effect of Vigiis 101 Lactic Acid Bacteria Powder on Body Weight and Body Fat in Overweight Participants), which is not on this map. Cited by 55 papers, 1 of them a synthesis that pooled it.
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.

Abstract
backgroundWe examined the prevalence of different obesity classes in South Korea based on the 2020 Obesity Fact Sheet.
methodsIndividuals ≥20 years who underwent a health examination provided by the Korean National Health Insurance System between 2009 and 2018 were included and the prevalence of class I, II, and III obesity was calculated for the total sample and age, sex, and region subgroups.
resultsFrom 2009 to 2018, the prevalence of all obesity classes increased across all sex and age groups and all regions. In the study population as a whole, the prevalence of class I, II, and III obesity was 29.1%, 3.2%, and 0.3% in 2009 and 32.5%, 5.2%, and 0.81% in 2018, respectively. Among young-aged individuals, the prevalence of each obesity class was 23.7%, 3.6%, and 0.44% in 2009 and 28.3%, 6.9%, and 1.61% in 2018, respectively. The prevalence among middle-aged individuals was 31.6%, 3.1%, and 0.24% in 2009 and 33.6%, 4.8%, and 0.59% in 2018; and among elderly individuals was 31.9%, 3.1%, and 0.21% in 2009 and 35.5%, 3.9%, and 0.32% in 2018. The increase in the prevalence of all obesity classes among young adults was dramatic. In particular, the class III obesity prevalence increased up to 3.8- and 3.5-fold between 2009 and 2018 in young men and women.
conclusionBased on the 2020 Obesity Fact Sheet, there was a dramatic increase in the prevalence of class II and III obesity from 2009 to 2018 among young adults, as well as the population as a whole. Optimal strategies for the prevention and treatment of obesity are needed considering the recent obesity epidemic in South Korea.
