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

introductionAlthough the relationship between taxation and conventional cigarette use is well established, little is known about the association with electronic cigarette (e-cigarette) use and no study has accounted for the potential delayed effects of e-cigarette policies beyond the observation period. This study aimed to evaluate the impact of China's 2022 e-cigarette tax increase on e-cigarette use.

methodsA prospective longitudinal observational design was utilized by collecting three-waves of online survey data in China. Participants were recruited through social media platforms. Baseline data were collected in October 2022, with follow-up survey conducted in March and August 2023. Participants were eligible if they were aged ≥18 years, reported using e-cigarettes in the past 30 days at baseline, and provided informed consent to be recontacted for follow-up. The Friedman test and the Cochran's Q test were used to assess differences across the waves. The Wilcoxon signed-rank test and the Tukey test were used to make pairwise comparisons between the groups.

resultsThere were 116 participants recruited at baseline and 91 (78.5%) of them complete all three surveys. E-cigarette use (ECU) decreased by 33.0% (95% CI: 23.7-42.3) in wave 2 after the tax increase was implemented, and by an additional 35.2% (95% CI: 26.8-43.7) in wave 3. The overall quit rate was 68.2% (95% CI: 60.3-75.9). However, 74.2% (95% CI: 65.9-82.5) of e-cigarette users whose quit switched to conventional cigarettes, resulting in an absolute cessation prevalence of only 17.6% (95% CI: 7.8-25.4). While perceived risk for ECU (χ

conclusionsThis study suggests a possible association between the China's 2022 e-cigarette tax increase and changes in e-cigarette use. However, its effectiveness was diminished due to the large number of e-cigarette users who switched to conventional cigarettes. China's 2022 e-cigarette tax increase also affected social norms regarding e-cigarette use and exposure to e-cigarette advertising. The findings may inform future policy considerations for a comprehensive strategy.
