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

BACKGROUND AND

aimsVapes are effective for smoking cessation. The UK Government launched the Swap to Stop initiative in England in December 2023, aiming to encourage people to quit smoking by providing free vape starter kits alongside behavioural support. This study aimed to assess the association between the introduction of Swap to Stop and the proportion of people in England who tried to quit smoking using vapes in the past year.

designData came from the Smoking Toolkit Study, a monthly cross-sectional population-based survey. The primary analysis used an interrupted time-series approach based on Autoregressive Integrated Moving Average (ARIMA) regression models.

settingTelephone interviews with people residing in private households in England between December 2021 and December 2024.

participantsPeople aged ≥16 years who smoked in the past year. MEASUREMENTS: The outcome was vape use during past-year quit attempts. The intervention effect was included as a step change in December 2023 to indicate the start of the Swap to Stop programme. The model also included a dummy variable to adjust for above-inflation tobacco tax increases.

findingsThe primary analysis indicated that the introduction of Swap to Stop in December 2023 was associated with a 1.5 absolute percentage point increase (adjusted B = 0.015, 95% confidence interval = 0.005-0.025) in the proportion of people in England using vapes in past-year quit attempts that persisted to December 2024.

conclusionsThe introduction of Swap to Stop (which provides free vape starter kits with behavioural support to quit smoking) in England appears to be associated with a statistically significant increase in quit attempts using vapes.
