Clinical Characteristics and Impact of Clostridium difficile Infection during Treatment of Rifampicin-Susceptible Pulmonary Tuberculosis.
Article in Tuberculosis and respiratory diseases, 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
backgroundAnti-tuberculosis (TB) treatment, although infrequently associated with Clostridium difficile infection (CDI), necessitates updated research on the incidence and clinical features of CDI among TB patients, especially as the demographic of older TB patients in South Korea is growing.
methodsA total of 168 patients with rifampin-susceptible pulmonary TB were enrolled in this study. Initial clinical features of the CDI-suspected group, risk factors for CDI, the primary outcome of all-cause mortality, and secondary outcomes, including delayed conversion of acid-fast bacillus (AFB) smear and culture, were analyzed.
resultsThe incidence rate of CDI among TB patients was 15.0 cases per 10,000 patient- days. Among initial features associated with TB-related CDI, patients exhibiting diarrhea of Bristol stool scale type 7 for more than 2 days were more likely to receive a CDI diagnosis. Old age and hypoalbuminemia were significant risk factors for CDI occurrence. In the primary outcome analysis, CDI was associated with a 4.63-fold increase in all-cause mortality according to the unadjusted analysis. However, this association dissipated in the adjusted analysis. Older age, underlying respiratory disease, and pneumonia at baseline were strong predictors of all-cause mortality. No significant factors were detected in the analysis of delayed AFB smear and culture conversion.
conclusionDespite the lack of an independent association between CDI and all-cause mortality among TB patients, monitoring older adults with undernutrition and persistent diarrhea for CDI is crucial.
