Physical multimorbidity and quit outcomes in a publicly funded smoking cessation programme.
Article in Internal medicine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesTo examine the association between physical multimorbidity and 6-month quit outcomes among treatment-seeking smokers.
methodsWe analysed data from 120 732 adults enrolled in Ontario's largest publicly funded smoking cessation programme. At enrolment, participants self-reported zero, one or two or more chronic physical health conditions. The primary outcome was 7-day point prevalence abstinence at 6 months. We used mixed-effects logistic regression to assess the association between multimorbidity and quit outcomes, adjusting for demographic and tobacco use characteristics.
resultsOf participants, 39.4% reported no conditions, 26.8% reported one and 33.8% reported two or more. Those with multimorbidity were older, had lower socioeconomic status and showed higher tobacco dependence but also greater motivation to quit. Compared to individuals without comorbidities, those with one condition (OR = 0.94, 95% CI: 0.90-0.98) and those with two or more (OR = 0.81, 95% CI: 0.77-0.85) had lower odds of quitting. Mental health conditions further reduced quit success among those with physical multimorbidity. DISCUSSION: Physical multimorbidity is associated with 19% lower odds of cessation success despite high motivation to quit. Tailored, intensive cessation support may improve outcomes for this high-risk group.
