Tuberculosis Development in Chronic Obstructive Pulmonary Disease: A Nationwide Population-Based Study.
Article in Journal of Korean medical science, 2026. 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
backgroundPulmonary tuberculosis is a major comorbidity of chronic obstructive pulmonary disease (COPD). However, the risk factors for tuberculosis development in patients with COPD have not been thoroughly studied. Thus, this study investigated the development of tuberculosis according to comorbidities and inhaler prescriptions for COPD.
methodsA retrospective cohort study was conducted using data from the Korean Health Insurance Review and Assessment Service database from January 1, 2015 to December 31, 2020. This cohort included 139,589 COPD patients (≥ 40 years) with a new prescription of inhalers. Cox proportional hazards regression models were used to identify significant risk factors for predicting the development of tuberculosis.
resultsMultivariate analysis demonstrated that a history of tuberculosis (hazard ratio [HR], 18.14; 95% confidence interval [CI], 16.44-20.02) and hospitalization during the screening period (HR for one hospitalization, 1.30; 95% CI, 1.17-1.44; HR for two or more hospitalizations, 1.54; 95% CI, 1.39-1.70), along with older age and male sex, were associated with the development of pulmonary tuberculosis.
conclusionOur data indicate that a history of tuberculosis and hospitalization during the screening period, along with old age and male sex, are independent risk factors for the development of pulmonary tuberculosis in patients with COPD.
