Comparison by detectable viral load (VL) status

Variable	Confirmed detectable VL a (n (%)/median (IQR)) n = 159	No confirmed detectable VL (n (%)/median (IQR)) n = 168	p
A. Study outcome confirmed detectable VL a versus no confirmed detectable VL
Male sex	86 (54)	84 (50)	0.460
Non‐perinatally acquired HIV	4 (3)	5 (3)	0.799
Age at ART initiation (years)	7.8 (4.3 to 10.2)	6.1 (2.6 to 9.6)	0.026
Age at study entry (years)	10.9 (10.0 to 13.6)	10.0 (10.0 to 12.5)	0.024
Follow‐up time in study (years)	5.1 (3.8 to 7.1)	4.7 (3.4 to 6.2)	0.021

Variable	At least one detectable VL (n (%)/median (IQR)) n = 216	Always undetectable VL (n (%)/median (IQR)) n = 111	p
B. At least one detectable VL (any VL> 100 copies/mL) versus always undetectable VL
Male sex	114 (53)	56 (50)	0.690
Non‐perinatally acquired HIV	4 (2)	5 (5)	0.165
Age at ART initiation (years)	7.6 (3.4 to 10.1)	5.2 (2.8 to 9.4)	0.048
Age at study entry (years)	10.7 (10.0 to 13.0)	10.0 (10.0 to 12.6)	0.266
Follow‐up time in study (years)	5.1 (3.7 to 7.0)	4.7 (3.5 to 6.1)	0.063

Variable	Always detectable VL (n (%)/median (IQR)) n = 16	At least one undetectable VL (n (%)/median (IQR)) n = 311	p
C. Always detectable VL (>100 copies/mlL versus at least one undetectable VL
Male sex	7 (44)	163 (52)	0.499
