Mobile instant messaging supported brief physical exercise intervention for smoking cessation: a community-based, cluster randomised controlled trial.
Trial report in Thorax, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05430451 (Building Capacity and Promoting Smoking Cessation in the Community Via "Quit to Win" Contest 2022), which is not on this 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.

Abstract
introductionPhysical exercise has been used to assist smoking cessation, but supervised programmes are bounded by limited scalability and generalisability. Mobile instant messaging (MIM) offers a scalable platform for delivering exercise support with minimal supervision. We assessed the effectiveness of MIM-supported brief physical exercise intervention on smoking cessation.
methodsIn this two-arm, parallel, cluster randomised controlled trial, we recruited daily smokers aged 18 years or older from 70 community sites in Hong Kong from June to October 2022. Sites were randomised (1:1) to either the intervention group (n=492) or control group (n=539). Brief cessation advice, physical exercise instructions and MIM-based practice reminders were offered to the intervention group for 3 months. The primary outcome was biochemically validated 7-day point prevalence abstinence (PPA) at 6 months.
resultsOf the 1031 participants (80.9% male, mean age 44.2 years), 59.8% were followed up at 6 months. Biochemically validated abstinence rates at 6 months were non-significantly higher in the intervention than the control group (10.4% vs 9.1%; risk ratio (RR) 1.14, 95% CI 0.79 to 1.66, p=0.48). Self-reported 7-day PPA was 21.9% and 19.5%, respectively (RR 1.13, 95% CI 0.89 to 1.43, p=0.32). Weekly practice of handgrip and elastic band exercises in the intervention group declined significantly over 6 months (from 10.3 min to 2.5 min and from 9.4 min to 0.8 min; p<0.001). The proportion of participants with moderate to high physical activity levels was quite similar between groups at 6 months (41.1% vs 39.9%; RR 1.05, 95% CI 0.82 to 1.35, p=0.70).
conclusionMIM-supported brief physical exercise intervention did not significantly increase smoking abstinence or physical activity compared with brief cessation advice alone. TRIAL REGISTRATION NUMBER: NCT05430451.
