Figure 1. Receiver operating characteristic curves for plasma drug concentration and the ability to detect drugs in the lungs for lamivudine (A) and efavirenz (B).

Figure 1

The areas under the receiver operating characteristic curves were 0.87 and 0.94 for 3TC and EFV, respectively (p < 0.0001 for both). The optimal plasma cut-offs suggested by the data are 178 ng/ml or less for 3TC and 2234 ng/ml or less for EFV.

EFV: Efavirenz; 3TC: Lamivudine.
