Risk of Cardiovascular Disease According to Standard Industrial Sectors: A Nationwide Longitudinal Study.
Article in Journal of Korean medical science, 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
backgroundCardiovascular disease (CVD) is a leading global cause of morbidity and mortality, with occupational factors significantly contributing to risk. However, industry-specific CVD risks in Asia remain understudied. This study evaluates CVD and all-cause mortality risks across industrial sectors in Republic of Korean (South Korea) using a nationally representative dataset.
methodsThis study examined middle-aged paid workers (aged 40-59 years) using data from the National Health Insurance Service database, which integrates biennial health screening data with insurance claims. We included individuals who underwent health examinations between 2009 and 2010 and followed them to identify CVD events through insurance claims records. Age-standardized incidence ratios were calculated using indirect standardization with the entire population as the control group, and 95% confidence intervals (CIs) were estimated using the Poisson distribution, with results stratified by sex. Population-attributable fractions were calculated to estimate each sector's contribution to the CVD burden.
resultsAmong males, the highest standardized incident ratios for CVD were observed in the "A. Agriculture, Forestry and Fishing" (1.20; 95% CI, 1.10-1.31) and "H. Transportation and Storage" (1.19; 1.17-1.21) sectors. For females, elevated standardized incidence ratios were found in the "D. Electricity, Gas, Steam and Air Conditioning Supply" (1.31; 1.09-1.57) and "H. Transportation and Storage" (1.15; 1.10-1.20) sectors. The "H. Transportation and Storage" sector showed the highest population-attributable fraction for males (3.34%), while the "I. Accommodation and Food Service Activities" sector led for females (1.64%).
conclusionThis study provides the first comprehensive analysis of industry-specific CVD risks in Asia, highlighting elevated risks in transportation possibly due to long working hours, sedentary behavior, and occupational stress. Targeted interventions are needed to address these occupational health disparities.
