Cox regression analysis of mortality in months 0 to 3, and from month 3 onwards.

*All patients with unknown HIV status died within the first 3 months.
£ Tests for interaction of TBM grade with treatment: p = 0.46 (months 0-3) and p = 0.18 (after month 3).
$ Tests for interaction of HIV status with treatment: p = 0.29 (months 0-3) and p = 0.17 (after month 3).
Gender and serum sodium were not significant in either model and didn't affect the other parameters. They were therefore omitted from the final mode.

* 所有HIV感染状态未知的患者均在首3个月内死亡。
£ 结核性脑膜炎（Tuberculous Meningitis, TBM）分级与治疗的交互作用检验结果：0至3个月区间的P值为0.46，3个月后区间的P值为0.18。
$ HIV感染状态与治疗的交互作用检验结果：0至3个月区间的P值为0.29，3个月后区间的P值为0.17。
性别与血清钠在两个模型中均无统计学意义，且未对其余参数产生影响。因此将其从最终模型中剔除。
