2. Fig. 1
Quality-adjusted life expectancy (QALE) of patients with operable (upper panel) and inoperable (lower panel) non-small-cell lung cancer (NSCLC). The survival curves (dotted lines), mean utility functions (dashed lines), and quality-adjusted survival curves (solid lines) of patients with NSCLC are shown, and the shaded area represents the QALE.

Quality-adjusted survival (QAS) curves of patients with operable (upper panel) and inoperable (lower panel) non-small-cell lung cancer and the corresponding referents. The shaded area between the QAS curve of patients and that of the corresponding referents is the loss-of-QALE (quality-adjusted life expectancy), which has been adjusted for lead-time bias (Table 2).

4. Fig. 3
Quality-adjusted life expectancy (QALE) and loss-of-QALE of patients with operable (upper panel) and inoperable (lower panel) stage IIIA non-small-cell lung cancer. The quality-adjusted survival (QAS) curves of patients (solid lines) and the corresponding referents (dotted lines) are shown. The blank area represents the QALE, whereas the shaded area represents the loss-of-QALE.
