Table 5. Viral Load and CD4 distributions of MACH14 sample.

First recorded viral load				Frequency		Percent
Undetectable (<50 copies/ml)				585		22.4
Detectable (≥50 copies/ml)				2,031		77.6
N	Mean	SD	Minimum	25th Percentile	Median	75th Percentile	Maximum

First recorded viral load (log10)^a
2,616	3.32	1.58	0	1.88	3.25	4.71	6.81
Viral load per subject (log10)^a
2,676	2.87	1.27	0	1.89	2.78	3.78	6.57

First recorded CD4
2,564	359	286	0	155	299	492	3,029
CD4 per subject
2,572	396	397	1	190	344	525	15,070

Viral load values are log10 based, and to make it non-negative, 1 is added before taking logarithms
