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
BACKGROUND AND
aimSubstance use disorders (SUDs) contribute significantly to global social and economic burden. Breathing-based interventions offer a low-cost, scalable adjunct or alternative to traditional treatment, yet their effects on substance use-related outcomes has not been systematically evaluated. This study aimed to systematically review and meta-analyse the effectiveness of controlled breathing and heart rate variability biofeedback (HRVB) interventions in improving substance use-related outcomes among people using alcohol and other drugs, including nicotine.
methodsWeb of Science, PsycINFO, MEDLINE, CINAHL, EMBASE, PubMed, Scopus and Cochrane were searched, with the final search conducted on 14 November 2025. The protocol was prospectively registered with the International Prospective Register of Systematic Reviews. Eligible studies were quantitative, with repeated-measure designs, with at least one substance use-related outcome; interventions were required to have controlled breathing as the primary mechanism and were categorised by inclusion of HRVB. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effects model was used to estimate pooled effects.
resultsOf 3502 studies identified, 20 met the inclusion criteria, of which 15 were eligible for meta-analyses. Breathing-based interventions produced lower craving than controls, with a small but statistically significant and consistent effect [Hedge's g = 0.30, 95% confidence interval (CI) = 0.12-0.48, heterogeneity (I
conclusionsIn people who use substances, breathing-based interventions appear to lead to statistically significant reductions in craving compared with controls, supporting their potential as a low-cost and scalable strategy for managing craving in substance use disorders.
