Prevalence and Associated Factors of Latent Tuberculosis Infection Among Healthcare Workers in a Mexican Tertiary Care Hospital.

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/
objectivesHealthcare workers (HCWs) are globally recognized as a high-risk group for tuberculosis (TB) infection. However, limited data exist on the prevalence of latent TB infection (LTBI) and associated occupational risk factors in the Mexican context. Identifying the burden of LTBI is essential for effective prevention. This study aimed to estimate the prevalence of LTBI among HCWs in a tertiary care hospital in Mexico and to explore associated risk factors.
methodsAn analytical cross-sectional study was conducted among 300 HCWs (including physicians, nurses, and stretcher-bearers) at a tertiary-level hospital in Mexico. Sociodemographic and occupational data were collected through a structured questionnaire. LTBI screening was performed using the tuberculin skin test (TST), with positive results confirmed via the QuantiFERON-TB Gold assay. Associations between relevant variables and LTBI were assessed using logistic regression models, adjusted for potential confounders.
resultsThe prevalence of LTBI was 16.7%. After adjusting for confounders, male HCWs had significantly higher odds of LTBI compared to females (adjusted odds ratio [aOR] = 2.02; 95% confidence interval [CI]: 1.06-3.80). Although elevated odds of LTBI were also observed among physicians, stretcher-bearers, and those with direct contact with TB patients, these associations were not statistically significant.
conclusionLTBI represents a relevant occupational health issue among HCWs, with nearly one in six workers affected. Early detection and prevention of TB in healthcare settings are critical to protecting individual workers and public health. These findings highlight the need to strengthen occupational TB surveillance and prevention strategies in similar healthcare environments.
