Demographic characteristics of study participants

	RSTR (n=9)	LTBI (n=10)	p-value
Number of adults (age ≥15 at phase 2)	7	10
Number of children (age <15 at phase 2)	2	0
Age at phase 2
Median age in adults (min, max)	28 (15, 52)	35 (16, 59)	0.59*
Median age in children (min, max)	7 (6, 8)	-
Sex (N female, %)	7 (77.8%)	6 (60.0%)	0.74∞
Exposure risk score at phase 1
Adults, median (IQR)	6 (6, 8.5)	6 (6, 6.8)	0.37*
Children, median (IQR)	8 (8, 8)	-
Median CD4 counts at phase 2 (IQR)	823 (567, 920)	558 (459, 666)	0.29*

Note. P-values were calculated using the Mann-Whitney test (*) for continuous variables and the chi-square test (^∞) for categorical variables. The exposure risk score was primarily measured during the initial study enrollment (phase 1, between 2002 and 2012), while other variables were measured during the first visit of the retracing study (phase 2, between 2014 and 2017) for each participant.
