Outcomes for smokers who develop melanoma: a systematic review and meta-analysis.
Article in EClinicalMedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: There is compelling evidence that the incidence of melanoma in cigarette smokers is substantially lower than in non-smokers. However, the risks of both recurrence and death appear to be higher in smokers if melanoma does develop. The magnitude of these increased risks is poorly documented. This systematic review aimed to analyse melanoma survival outcomes among smokers compared to never-smokers using published studies, and report the magnitude of any survival differences. Methods: Searches of Medline, Embase and Cochrane CENTRAL (to 11/03/2024) using terms for melanoma and smoking were conducted. Included studies were those reporting outcomes including disease severity at presentation, risk of death or adverse effects from treatment in smokers and never-smokers with melanoma. No study design or language restrictions were imposed. Risk of bias was assessed using the Newcastle-Ottawa tool. The review protocol was registered with PROSPERO (ID CRD42024518505). Findings: Forty-six studies involving 164,166 melanoma patients, of whom 70,766 had smoked cigarettes, were identified. The pooled individual Hazard Ratios (HR) from multivariable analyses, showed that death from melanoma was 33% higher in current compared to never-smokers (HR 1.33, 95% CI 1.14-1.55, p = 0.0002, 13,971+ patients) with limited heterogeneity (I Interpretation: Current smokers are more likely to die from their melanoma than never-smokers, while former-smokers appear to have similar risks to never-smokers. Smokers have higher risks of sentinel node-positivity and of complications from node surgery. Study limitations included reliance on self-reporting of smoking status. In only seven studies did patients receive modern systemic therapies, limiting the ability to assess their relative efficacy in smokers and non-smokers. Funding: None.
