A Retrospective Study of Treatment Patterns and Clinical Outcomes in Patients With Central Nervous System Tuberculosis

Study Overview
=================
Brief Summary
-----------------
This is a retrospective clinical study to analyze the clinical characteristics, complications, and effects of different treatment options on long-term prognosis in patients with central nervous system tuberculosis. All cases of central nervous system tuberculosis diagnosed between 2016 and 2021 were included in the electronic medical record system of one center, and data such as demographics, hospitalization information, clinical information, laboratory or imaging examinations, treatment plans, and outcomes were collected.
