Intrathecal therapy
ProcedurePatients who underwent at least one lumbar puncture and spinal canal administration of glucocorticoids during hospitalisation were classified as receiving intrathecal (IT) therapy. Dexamethasone was the glucocorticoid administered intrathecally at a dose of 5 mg per administration. All patients also received oral or intravenous anti-TB regimens, which included at least isoniazid and rifampicin for drug-sensitive TBM cases. Patients diagnosed with or suspected of having drug-resistant TBM who required second-line anti-TB drugs were excluded from the study.
