P-values represent:
Comparison between all TB cases and all controls.
Comparison between IL13 positive cases and all controls.
Comparison between IL13 positive cases and IL13 negative cases.
Tested by Fisher's Exact Test.
Tested by Mann–Whitney U test (using exact significance).
Numbers too small to calculate median and IQR.
NA = these represent the 2 TB cases with EPTB; this category was excluded from analysis comparing IL13 positive and IL13 negative cases.
Both culture negative TB cases responded to treatment.
A p24 ELISA was done for all cases and controls sampled before 1997, and a RNA test was done for all cases and controls sampled thereafter.
