Table 2. Case-control sample characteristics and TB susceptibility modelling results.

	TB Cases (n = 398)	Controls (n = 360)	p value*
Age (mean ± SD)	36.55 ± 11.26	30.69 ± 12.80	0.0001
Number of males (proportion)	211 (0.53)	111 (0.28)	< 0.0001
KhoeSan [IQR]	0.30 [0.20–0.39]	0.27 [0.18–0.36]	0.0224
West African [IQR]	0.27 [0.16–0.39]	0.25 [0.15–0.37]	0.3187
European [IQR]	0.18 [0.08–0.28]	0.19 [0.12–0.28]	0.7804
South Asian [IQR]	0.12 [0.03–0.19]	0.14 [0.06–0.22]	0.2767
East Asian [IQR]	0.09 [0.03–0.16]	0.10 [0.05–0.17]	NAa

^a The East Asian component was not added to the model to avoid linear dependency.
