Demographic data of patients with confirmed TB.

Demographics*	Stage I (N = 42)	Stage II (n = 12)	p-value
Age, years	76.0 (64.0,81.3)	75.5 (70.0,85.0)	0.312
Gender, Male (%)	28 (66.7%)	9 (75.0%)	0.732
Duration of cough, days	7.0 (5.0,7.25)	8.0 (7.0,9.0)	0.038†
From alarm to diagnosis, days	14 (3, 26)	12.5 (5.0,19.0)	0.950
Smear-culture result
Smear negative, culture positive	21 (50%)	6 (50%)	1.000
Smear positive, culture positive	21 (50%)	6 (50%)

* Demographics were summarized as median (Q1,Q3) for age, duration of cough, time from alarm to diagnosis with non-parametric Wilcoxon rank-sum test, and as n (%) for gender, outcome of smears and cultures with Chi-square/or Fishers' exact test.

^† p-value < 0.05 indicated the duration of cough (days) was significantly higher in stage II than stage I.
