Effectiveness of an in-office intervention to improve general practitioners' support for tobacco smoking cessation: results from a randomised controlled trial (TABAC-PRO).
Trial report in BMC primary care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAlthough support for tobacco smoking cessation provided by general practitioners (GP) has proven effective, such an approach remains quite rare. We designed a behavioural science-based intervention to improve GP support for patients to quit smoking. The present study aimed to evaluate the effectiveness of this in-office paper-based intervention by comparing it with a no-intervention control group.
methodsWe conducted an online randomised controlled trial between January and May 2024 among GPs in France. The intervention consisted in sending a kit containing an information sheet for GPs outlining the main stages of brief advice for smoking cessation, questionnaires for patients asking them about their smoking status and, for those who smoked, their motivation to quit, as well as a poster to be displayed in each GP's waiting room to encourage people who smoke tobacco to complete the questionnaire. The primary outcome was the proportion of people who smoke with whom GPs had discussed smoking cessation on their last full working day five weeks after the kit had been sent out. The secondary outcome was the likelihood that GPs provided cessation support (e.g., prescribed nicotine replacement therapy (NRT), proposed a follow-up consultation, and/or referred patients to other professionals) on the same day.
resultsOf the 800 GPs recruited, 641 fully completed the final survey (333 in the intervention group and 308 in the control group). The proportion of people who smoke with whom GPs had discussed cessation was significantly higher in the intervention group (59.0% vs. 52.3%, p < 0.05). The likelihood of a follow-up consultation being offered to patients who smoke was also significantly higher in the intervention group (73.8% vs. 60.3%, p < 0.05). The likelihood of NRT prescription or referral were not significantly different between groups (82.4% vs. 77.9%, and 23.3% vs. 21.5%, respectively).
conclusionsProviding simple paper-based tools was associated with a greater likelihood of GPs discussing smoking cessation with their patients. This kind of intervention could usefully complement other primary care interventions, for example training, remuneration and financial incentives or care pathway reorganisation, with a view to significantly decreasing smoking prevalence.
