1 · What the graph read from it

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.

2 · The registry

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

introductionSmoking and obesity are leading risk factors for morbidity and mortality worldwide. Recent studies have demonstrated the efficacy of glucagon-like peptide-1 (GLP-1) receptor agonists in reducing weight and improving metabolic outcomes. Emerging evidence suggests that these agents may also influence reward-related pathways, offering potential benefit for nicotine addiction and mitigating post-cessation weight gain. This study aimed to evaluate the efficacy of GLP-1 receptor agonists for smoking cessation and their effects on post-cessation weight and BMI.

methodsA systematic review and meta-analysis of randomized controlled trials was conducted, with the literature searched through November 2025 in PubMed, Scopus, the Cochrane Library, and Web of Science. Eligible studies included adult smokers (Population) receiving GLP-1 receptor agonists (Intervention) compared with placebo or standard care (Comparator), reporting smoking cessation and/ or post-cessation weight or BMI outcomes (Outcomes). Random-effects models were used to pool data, with odds ratios (ORs) for abstinence and weighted mean differences (WMDs) for weight and BMI, and heterogeneity assessed using the I

resultsOf the 751 records screened, 26 full texts were reviewed, and two randomized controlled trials (n=337) were included. Compared with placebo, GLP-1 receptor agonists showed no significant effect on smoking cessation (OR=1.36; 95% CI: 0.55-3.35, p=0.51; I

conclusionsWhile GLP-1 receptor agonists have revolutionized the treatment of diabetes and obesity, their role in smoking cessation remains inconclusive. However, reductions in post-cessation weight and BMI highlight their potential as adjunctive agents to address weight-related relapse risk. Larger, longer duration trials with newer GLP-1 agents are warranted to confirm these findings and clarify their role in smoking cessation.
