Association between smoking status and death from COVID-19 in South Korea: A nationwide cohort study.
Article in Tobacco induced diseases, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionThis study examined the association between smoking status and death from COVID-19.
methodsThis study used nationwide cohort data collected from the Korean National Health Insurance Service, linking to information on all individuals who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The smoking status of subjects who participated twice in national health screenings between 2015 and 2018 was measured. This study investigated death from COVID-19 among those who tested positive from 1 January to 30 May 2020.
resultsThis study included 4259 patients who tested positive for SARS-CoV-2 in Korea. After adjusting for all potential confounding factors, current smokers (adjusted odds ratio, AOR=3.75; 95% CI: 1.23-11.36) and recent quitters (AOR=3.74; 95% CI: 1.12-12.53) were associated with an increased risk of death from COVID-19 compared to never smokers. Compared with current smokers, long-term quitters (AOR=0.33; 95% CI: 0.11-0.95) and never smokers (AOR=0.27; 95% CI: 0.09-0.81) were associated with a reduced risk of death from COVID-19.
conclusionsSmoking was associated with an increased risk of death among patients with COVID-19. Given the lower possibility of death in long-term quitters with COVID-19, continuous smoking cessation among smokers or recent quitters is needed.
