The association of incident abdominal obesity with diet and unfavorable lifestyle factors in Korean adults: A prospective cohort study.
Observational study in Medicine, 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
Unhealthy lifestyles are strongly associated with the development of cardiometabolic diseases and the risk of all-cause mortality. We hypothesized that unhealthy lifestyles including poor diet contribute to the development of cardiometabolic diseases. This study aimed to investigate the incidence of metabolic syndrome (MetS) and its clustering components in relation to diet and lifestyle risk factors in Korean population. At baseline, all participants (n = 2000) completed a general health-related questionnaire, provided blood samples, and underwent health examinations. Lifestyle factors were investigated including smoking, alcohol consumption, physical activity, sleep, dietary quality, and weight status. Cox proportional hazard regression was used to estimate the hazard ratio (HR) and 95% confidence intervals (CIs) of primary endpoints: MetS events and their clustering components. A total of 1697 participants (mean age: 43.8 ± 0.2 years) were included, of whom 72.4% (n = 1228) were women. Compared to the healthy group, unhealthy participants had a significant HR value of abdominal obesity for lifestyle factors (HRs: 1.937, 95% CI: 1.335-2.810). No significant differences were observed between MetS and other clustering components. After adjusting for covariates, the lowest quintile of vitamin C (HRs: 1.553, 95% CI: 1.153-2.091), fiber (HRs: 1.409, 95% CI: 1.035-1.919) and vegetable intake (HRs: 1.300, 95% CI: 1.008-1.678) were significantly associated with abdominal obesity incidence compared with the highest quintile. Adherence to healthy lifestyle factors and dietary factors, such as high intakes of vitamin C and vegetables, were negatively associated with the incidence of abdominal obesity among the MetS components in Korean adults.
