A systematic review of smoking cessation interventions tested among Indigenous populations in the United States.
Synthesis in Journal of substance use and addiction treatment, 2025. 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
introductionSmoking remains highly prevalent among Indigenous populations in the U.S., contributing to cardiovascular and cancer health disparities. Tailored smoking cessation interventions can reduce these disparities among Indigenous people, but the current evidence regarding the effectiveness of such extant interventions is unclear. This review aimed to collate evidence about the smoking cessation interventions tested among Indigenous groups in the U.S.
methodsThe study systematically searched PubMed, EMBASE, and Web of Science in September 2023 for experimental or quasi-experimental studies of smoking cessation interventions among Indigenous adults in the U.S. The Cochrane guidelines assessed study bias. Outcomes included self-reported and bio-verified smoking abstinence.
resultsThe review included eight studies, comprising 7 randomized control trials (RCTs) and 1 quasi-experimental trial evaluating multi-component interventions. The interventions included counseling, education, cultural tailoring, pharmacotherapy, mobile medical apps, and social media. The smoking abstinence outcomes varied. Four RCTs found no significant differences in self-reported or bio-verified abstinence between groups. Two RCTs showed significantly higher self-reported abstinence with culturally tailored interventions, while two postpartum RCTs found no difference between groups. The one-group quasi-experimental study showed a retention rate of 71 % and an abstinence rate of 31 % at 6-month follow-up. While results appear promising for tailored, multi-faceted approaches, abstinence differences between interventions and control groups overall remain inconsistent.
conclusionsThis review suggests that culturally tailored, technology-assisted smoking cessation interventions that strategically utilize pharmacotherapies may hold promise for U.S. Indigenous populations. However, the review emphasizes the need to test large-scale interventions that utilize more personalized strategies and community-based participatory approaches as well as the need for experimental trials that bio-verify abstinence.
