Trends of Electronic-Cigarette and Heated Tobacco Product Use Among Korean Adults From 2013 to 2023: A Cross-Sectional 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
backgroundWhile awareness and use of electronic cigarettes and heated tobacco products (EC/HTP) have increased in Korea over the past decade, studies on the yearly prevalence of such use are limited, as are those identifying factors associated with their use.
methodsIn this study, we analyzed the prevalence, trends, and factors associated with EC/HTP use over a 10-year period (2013-2023) using the Korea National Health and Nutrition Examination Survey. The yearly prevalence of EC/HTP use was assessed, and factors related to EC/HTP use were identified.
resultsOver the study period, EC/HTP use increased, especially use by males and younger study subjects, to 7.3% in 2023. While conventional cigarette use declined consistently from 24.1% in 2013 to 18.7% in 2023, EC/HTP use fluctuated; however, the overall trend was increasing, particularly among individuals in their 20s and 30s. Groups associated with EC/HTP use as identified on multivariable analyses were former smoking (adjusted odds ratio [aOR], 66.01;
conclusionEC/HTP use in Korea has risen significantly, particularly among younger males, and conventional cigarette use has declined. Key factors include ever-smoking status, younger age, male, elevated BMI, unmarried, and specific occupational roles. These trends highlight the need for targeted interventions and public health strategies to address shifting modes of tobacco use.
