Assessing the Causal Relationship between Chronic Obstructive Pulmonary Disease and Tuberculosis: A Mendelian Randomization Study.
Article in International journal of chronic obstructive pulmonary disease, 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
Background: Chronic obstructive pulmonary disease (COPD) and tuberculosis are both significant global public health challenges. The co-occurrence of these two diseases is frequently observed in clinical settings. However, their causal relationship remains unclear. Methods: We utilized genome-wide association study (GWAS) datasets to conduct bidirectional two-sample Mendelian randomization and multivariable Mendelian randomization analyses. We first analyzed COPD data from the FinnGen consortium (n = 193,638) and tuberculosis data from a genetic association study (n = 484,598). In the second phase, we stratified COPD patients by age into the EARLY COPD group (Event_Age < 65) and the LATER COPD group (Event_Age ≥ 65) to explore their causal relationships with tuberculosis separately. We then validated these results using tuberculosis data from MRC-IEU (n = 462,933). Finally, smoking and COPD-related SNPs as instrumental variables were analyzed by multivariable Mendelian randomization to further investigate the association between COPD and tuberculosis. Multiple methods were used in the Mendelian analyses to ensure a comprehensive and rigorous investigation. Results: In the initial analysis phase utilizing the inverse variance weighting (IVW) method, tuberculosis showed no significant contribution to the incidence of COPD (IVW odds ratio (OR) = 0.9961; 95% confidence interval (CI) = 0.9828-1.0095; P = 0.564). Conversely, COPD appeared to significantly increase the risk of developing tuberculosis (IVW OR = 1.0008; 95% CI = 1.0001-1.0014; P = 0.015), particularly in patients under 65 (IVW OR = 1.0008; P = 0.011). Conclusion: This Mendelian randomization analysis found that COPD may increase the risk of tuberculosis, while tuberculosis does not increase the risk of COPD, suggesting the necessity of enhancing prevention and screening efforts for tuberculosis among COPD patients, especially younger individuals.
