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

backgroundThe French-speaking Society for Smoking Cessation (Société francophone de tabacologie, SFT), which promotes scientific knowledge and training on smoking cessation, asked us to identify and quantify consensual agreements among its members on the use of e-cigarette for smoking cessation.

methodsWe used the fast-track Delphi process, starting with a modified version of the Nominal Group Technique where experts generated propositions to answer the target question: "What is the place and usefulness of vaping in the clinical care of people who smoke?", followed by two Delphi surveys (e-questionnaires), in which they expressed their opinion on each statement (9-point Likert-scale) and commented. Consensual agreement is reached on a statement with a median ≥ 7 on the 1-9 Likert-scale (agreement) and an interquartile range (IQR) ≤ 3 scale points (consensus).

resultsOver 40 days in autumn 2023, 87/163 (53%) experts reached consensual agreement on 26/33 (79%) statements, notably on the main outcome "According to current data, the e-cigarette is effective for smoking cessation (abstinence of 6 months or more)" (median 7, IQR 6.5-7.5). They considered that e-cigarette very likely reduces the risks compared to smoking (8, 7-9), and "can be used in association with nicotine replacement products" (9, 8-9). No consensual agreement was reached for adverse effects and potential benefits for subgroups (i.e. pregnancy, hospitalized).

conclusionsParticipating experts agreed that e-cigarette can help to quit smoking. Agreeing on priority actions for smoking cessation is a base to develop clinical guidelines and trainings, and to tackle the industry-led tobacco epidemic.
