Predictors of smoking abstinence among diabetic smokers: Evidence from the French national smoking cessation registry CDTnet.
Article in PloS one, 2025. 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
Evidence suggests that diabetic smokers are less likely to quit smoking when compared to non-diabetic smokers. This study aimed to determine predictors of abstinence among diabetic smokers attending smoking cessation services (SCSs) across France. We analysed data from 94,827 adult smokers registered in the French national smoking cessation registry (CDTnet) between 2007 and 2016. Participants attended ≥2 SCS visits, and one-month continued abstinence was confirmed by carbon monoxide measurement. Among 6,405 diabetic smokers, 33% achieved one-month continued abstinence, versus 38% among 88,422 non-diabetic smokers (p < 0.001). Positive predictors of abstinence among diabetic smokers included employment (odds ratio [OR], 1.61; 95% confidence interval [CI], 1.37-1.89), ≥ 3 prior quit attempts (OR, 1.61; 95% CI, 1.36-1.91), low nicotine dependence (OR, 1.42; 95% CI, 1.13-1.78), prescription of combined nicotine replacement therapy (NRT) (OR, 1.43; 95% CI, 1.19-1.72) or varenicline (OR, 1.64; 95% CI, 1.20-2.25), and ≥7 SCS consultations (OR, 4.47; 95% CI, 3.40-5.84). Conversely, negative predictors included history of myocardial infarction/angina (OR, 0.82; 95% CI, 0.70-0.96), chronic bronchitis/chronic obstructive pulmonary disease (OR, 0.79; 95% CI, 0.69-0.91), anxiety (OR, 0.82; 95% CI, 0.71-0.94), recent cannabis use (OR, 0.67; 95% CI, 0.50-0.90), and exclusive oral NRT use (OR, 0.70; 95% CI, 0.56-0.88). Overall, tailored cessation programs are crucial for enhancing cessation outcomes among diabetic smokers.
