Tuberculous meningitis (TBM) is the most lethal form of tuberculosis (TB). While anti-TB regimens remain the cornerstone of treatment, spinal injection of dexamethasone is considered a potentially effective adjuvant therapy. However, its impact on mortality and disability remains uncertain. This study analysed all TBM patients admitted to Beijing Chest Hospital affiliated with Capital Medical University from January 1, 2010 to December 31, 2023. Patients were categorised into two groups based on whether they received standard anti-TB therapy with dexamethasone via spinal canal administration (intrathecal therapy group) or standard anti-TB therapy alone (non-intrathecal therapy group). Propensity score matching was used to balance baseline characteristics, and one-year mortality and severe disability rates were statistically compared between the groups.
