^aQVOA values are presented and represent the presence or absence of positive wells with fewer than 50 SIV RNA copies/ml of supernatant. Values reflect maximum likelihood estimates of infection frequency in IUPM (infectious units per million cells). Given the resolution of the assay, the 95% confidence interval is typically 0.2 to 4 times the reported value.
