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
backgroundOur primary aim was to assess-in the German population-the effectiveness of e-cigarettes (ECs; with or without nicotine), nicotine replacement therapy (NRT), and no use of evidence-based aids in smoking cessation.
methodsAnalysis of cross-sectional data from a representative survey of the population (age 14-96 years) conducted in 2016-2021. All current smokers and recent ex-smokers (< 12 months since quitting) who had made ≥ 1 attempt to quit in the past 12 months (n = 2740) were included. They were asked about use of cessation aids in their most recent quit attempt and their current smoking status.
resultsTwo hundred thirty-nine respondents had used ECs, 168 NRT, and 2333 no aid. After adjustment for potential confounders, the odds of abstinence were 1.78 times higher for smokers who had used ECs in their quit attempt than in the group that had used no aids (95% confidence interval [1.09; 2.92]; p = 0.02) and 1.46 times higher than in the NRT group ([0.68; 3.13]; p = 0.34, Bayes factor = 1.26). Compared with the unaided group, the odds of abstinence were 2.34 times higher ([1.21; 4.53]; p = 0.01) in the subgroup using ECs with nicotine and 1.48 times higher ([0.68; 3.26]; p = 0.33) in the subgroup using ECs without nicotine. The unadjusted abstinence rates in people who had started their quit attempt > 6 months earlier were 15.6% [9.4; 23.8] in the ECs group and 13.8% [7.3; 22.9] in the NRT group.
conclusionIn Germany, use of ECs in an attempt to quit smoking is associated with a higher rate of abstinence than attempting to quit unaided.
