Pharmacological Interventions for Electronic Cigarette Cessation: A Systematic Review and Meta-analyses.
Synthesis in Journal of addiction medicine. 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
objectivesThe rising global prevalence of electronic cigarette (e-cigarette) use poses significant public health concerns, including nicotine dependence. This systematic review and meta-analysis evaluated the efficacy and safety of pharmacological interventions for e-cigarette cessation.
methodsWe systematically searched 5 databases, including Cochrane Library, PubMed, Ovid Embase, Sinomed, and Web of Science Core Collection, up to May 1, 2024, that evaluated the efficacy and safety of pharmacological intervention compared with placebo for e-cigarette cessation. Two investigators independently screened studies, extracted data, and assessed the risk of bias. The outcomes of interest were (1) continuous abstinence rate (CAR); (2) 7-day point prevalence of e-cigarette abstinence at different weeks; and (3) adverse effects. This study was registered with PROSPERO (CRD42024577356).
resultsOf 1567 initially identified records, 7 studies involving 1161 participants were included. Most studies had a low risk of bias. The results indicated that varenicline (4 studies, n=463; OR=2.52, 95% CI: 1.14-5.58) was effective, while the effect of nicotine replacement therapy (NRT; 2 studies, n=538; OR=1.38, 95% CI: 0.61-3.14) was not statistically significant. One study on cytisine also suggested potential benefit.
conclusionsVarenicline has demonstrated efficacy in supporting e-cigarette cessation, whereas the current evidence for NRT and cytisine remains insufficient to draw firm conclusions. Further well-designed studies are needed to clarify the effectiveness of these 2 interventions. Although pharmacotherapies used for cigarette smoking show potential for repurposing, their utility in e-cigarette cessation should be interpreted cautiously until stronger evidence becomes available.
