Association of smoking with depression among tuberculosis patients: a systematic review and meta-analysis.
Synthesis in BMC public health, 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
backgroundThe co-occurrence of smoking and depression presents a significant public health concern, particularly among individuals with tuberculosis (TB). Smoking delays the recovery from tuberculosis (TB) and it has also been associated with depression in those who have been diagnosed with the disease. The review aimed to find out the association between smoking and depression among TB patients.
methodsA systematic review and meta-analysis were conducted following PRISMA guidelines, in PubMed, Scopus, and ScienceDirect databases. Literature searches were employed using terms related to "tuberculosis", "smoking," and "depression" across all articles either by title, abstract, or keywords. To evaluate the risk of bias, the Joanna Briggs Institute Critical Appraisal Checklist (JBI) was used. For clinical heterogeneity, a meta-analysis was conducted to pool estimates using RevMan 5.3 and Stata 13.0 software was used for publication bias assessment.
resultsFrom the 1393 studies identified, eleven studies were eligible for inclusion in this study. There were nine cross-sectional, and two cohort studies. Only 5 studies reported effect size calculation suitable for multivariate analysis. The pooled analysis indicates that smoking TB patients were associated with a higher odds of depression (OR = 2.56, 95% CI: 1.11-5.92), though the wide confidence interval and substantial heterogeneity (I² = 71%, p = 0.003) indicates uncertainty regarding the effect size. Subgroup analysis based on depression assessment tools revealed a stronger association between smoking TB patients with depression (OR = 3.36; 95% CI: 1.19-9.50) with high heterogeneity (I² = 75%). Publication bias, as indicated by Egger's test (bias coefficient = 0.59, p = 0.874).
conclusionsExisting evidence suggests a potential association between depression and smoking among tuberculosis patients, which encourages more studies to explore whether smoking cessation would contribute to the improvement of mental health outcomes in this population.
