Effectiveness of mobile smoking cessation treatment with 1-week nicotine replacement therapy sampling at outdoor smoking hotspots: A cluster randomized controlled trial.
Trial report in Addiction (Abingdon, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimsTo evaluate the effectiveness of mobile smoking cessation (SC) treatment with 1-week nicotine replacement therapy (NRT) sampling on recruitment and quitting outcomes.
designTwo-arm cluster RCT (1:1 ratio), single-blinded, at 244 recruitment sessions in Hong Kong outdoor smoking hotspots from October 2018-December 2019.
settingParticipant were recruited by ambassadors and treated at the mobile SC truck.
participants834 adult (≥18 years, male 81.3%) daily smokers, Chinese-speaking, non-NRT users in the past month, consented after nurse-led intervention in mobile SC truck were randomized to the experimental (n = 482 male 79.5%) and the control group (n = 352, male 83.8%). INTERVENTION AND COMPARATOR: The experimental group received a 1-week free NRT sample, an NRT instruction card, and mobile SC treatment including onsite nurse-led brief medication advice (about 15 minutes) and referral to SC clinics. The control group received the same mobile SC treatment. MEASUREMENTS: Primary outcome was self-reported quit attempts at 1-month follow-up. Secondary outcomes included SC service use at 1 month, and biochemically validated abstinence (exhaled carbon monoxide < 4 ppm; or saliva cotinine < 10 ng/ml) at 6-month follow-up. Additionally, a post-hoc cost analysis was conducted.
findingsBy intention-to-treat, the two groups showed similar prevalence of quit attempts (44·4% versus 43·5%, risk ratio (RR) = 1·04, 95% confidence interval (CI) = 0·79-1·37, P = 0·79). Compared with the control group, the experimental group showed lower SC service use at clinics (32·4% versus 44·9%, RR = 0·72, 95%CI = 0·57-0·91, P = 0·006), but no significant difference in validated abstinence (4·6% versus 2·8%, RR = 1·64, 95%CI = 0·76-3·50, P = 0·21). The experimental recruitment sessions recruited more smokers for onsite medication advice than the control session (mean 6·7 vs 5·0, adjusted incident rate ratio = 1·30, 95%CI = 1·08-1·56, P = 0·005).
conclusionsMobile smoking cessation treatment with 1-week nicotine replacement therapy sampling did not increase quit attempts or abstinence outcomes among recruited daily smokers in Hong Kong. The intervention increased smokers' uptake of onsite medication advice but reduced subsequent smoking cessation service use at clinics.
