Tobacco and Nicotine Consumption and the Motivation to Stop Smoking in Smokers With and Without Coronary Heart Disease: A Comparative Analysis of Two Cross-Sectional Studies.
Observational study in Deutsches Arzteblatt international, 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
backgroundSmoking worsens the prognosis of patients with coronary heart disease (CHD). Only limited population-based data are available on smoking cessation and its characteristics in people with CHD. We compared smokers with and without CHD.
methodsWe analyzed pooled data from nine waves (June 2023-August 2024) of two representative cross-sectional surveys in Germany (DEBRA and OptiCor). We included adults aged 35 years and above who provided information on their smoking behavior and CHD status (n = 11 069; 994 [9%] with CHD). The endpoints included smoking status, tobacco dependence, motivation to quit smoking, and attempts to do so, as well as the use of electronic inhalation products (e-cigarettes, tobacco heaters). Regression models with CHD as an independent variable were adjusted for age, sex, education, and income.
resultsPeople with CHD were less likely to be current smokers (23.8%, 95% confidence interval [21.2; 26.6], versus 29.3% [28.5; 30.2]), but they were more likely to be former smokers (32.2% [29.3; 35.3] versus 18.9% [18.1; 19.6]). Being a smoker with CHD was associated with the use of electronic inhalation products (odds ratio [OR] = 2.53 [1.43; 4.48]), higher motivation to quit smoking (OR = 1.41 [1.02; 1.96]), and greater tobacco dependence (OR = 1.63 [1.05; 2.53]). Among current smokers and those who smoked in the past year, those with CHD were also more likely than those without CHD to have made at least one attempt to quit in the past year (OR = 2.90 [1.98; 4.25]).
conclusionOne-quarter of people with CHD smoke. Despite a greater degree of tobacco dependence, they show higher motivation and make more attempts to quit smoking compared with smokers without CHD. As smoking cessation is crucial in this group, healthcare professionals should consistently assess the smoking status of people with CHD and offer them evidence-based support for smoking cessation.
