Comparison of median IFN-γ responses in all TB suspect children.

Comparison of median IFN-γ in subgroups of children, finding lower median levels in response to specific TB antigens in children †Wilcoxon’s rank-sum test used to test differences in median IFN-γ between subgroups of children, pIQR: interquartile range.*Living PTB+ defined as living in the same household as a person with smear positive pulmonary TB.**Clinically diagnosed with TB and put on anti-TB therapy.***Subcategory “healthy” used for comparison both for “ill” and “died”.

儿童亚组干扰素γ（IFN-γ）中位数水平比较分析，结果显示部分儿童在特定结核病（TB）抗原刺激下的干扰素γ中位数水平更低。
† 采用Wilcoxon秩和检验（Wilcoxon’s rank-sum test）检验儿童各亚组间干扰素γ中位数水平的差异，pIQR：四分位间距（interquartile range）。
* Living PTB+ 定义为与痰涂片阳性肺结核患者共同居住的人员。
** 经临床确诊结核病并接受抗结核治疗的受试者。
*** 亚组"健康人群"用于与"患病组"及"死亡组"进行对照比较。
