Abstract
Objective: To identify predictive factors for extra-pulmonary tuberculosis (EPTB) occurrence amongst tuberculosis individuals in Pakistan.
Methodology: This retrospective study was conducted in three hospitals in Pakistan. After data collection, association analysis was done via Pearson’s chi-squared (χ2) test, and univariate and multivariate regression models were used to evaluate odds ratios for estimating EPTB risk predictors.
Results: We identified 318 EPTB individuals in 2000 of the overall TB subjects. Within extrapulmonary sites, the most common were the pleural cavity (58%). The strongest predictors for EPTB were age (0-5 years) [p=0.007, OR=3.01(1.31-6.56)] and disease relapse.
Conclusion: Our study identified significant clinical and hematological characteristics associated with EPTB. Age (0-5 years) and disease relapse are suggested predictors for EPTB, highlighting the need for targeted interventions in high-risk groups.

Key words: Extra-pulmonary tuberculosis, epidemiology, risk factors, tuberculosis.
