Effect of cognitive behavior therapy on abstinence among healthy smokers: a systematic review and meta-analysis of randomized controlled trials.

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
backgroundThe objectives of this review and meta-analysis were twofold: first, to critically evaluate the effectiveness of cognitive behavioral therapy (CBT)-based interventions relative to standard care or control conditions in promoting smoking abstinence at the end of treatment, and second, to determine abstinence rates at 3 and 6 months of follow-up.
methodsA comprehensive search of electronic databases, including PubMed, Cochrane Library, PsycINFO, Embase, and ClinicalTrials.gov, was conducted for randomized controlled trials published from 2001 to September 2024. Studies evaluating the effect of CBT on abstinence rates among healthy smokers (aged ≥12 years) were included and analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
resultsOut of 1,514 study records screened, 7 studies (comprising 17 arms and 1,438 participants) met eligibility criteria for inclusion in the final analysis. The pooled analysis revealed that CBT significantly improved smoking abstinence rates, demonstrating a fourfold increase in effectiveness compared to controls (odds ratio [OR], 4.04; 95% confidence interval [CI], 2.73-5.99; I2=19%; p<0.00001). Additionally, CBT significantly impacted smoking cessation at 3-month follow-up (OR, 1.62; 95% CI, 1.11-2.38; I2=0%; p=0.01) and 6-month follow-up (OR, 2.19; 95% CI, 1.59-3.00; I2=0%; p<0.00001).
conclusionCBT has demonstrated efficacy in facilitating smoking abstinence, particularly immediately after treatment, with sustained but diminished effects over time. However, robust conclusions on the efficacy of CBT require further studies involving larger sample sizes, diverse geographical regions, and longer follow-up periods.
