FIG. 2.

Prediction of plasma (PL) VL from WB VL (n = 147). cp or cop, copies. Of note, some of the viral DNA loads in plasma were undetectable (i.e., left-censored) and are plotted at the detection limit (2.70 log₁₀ copies/ml); however, they were taken into account as left-censored values in the model (see Materials and Methods).
