Figure 1. Constructs for the experimental conditions.

Figure 1

The non-SOS condition presents without a pulmonary nodule (A) and the SOS condition presents with a pulmonary nodule (B). The same native abnormality, a Zenker’s diverticulum with residual barium, appears in both A (white arrow) and B. A simulated pulmonary nodule has been digitally placed in B (white arrow). In all other respects the two images are identical.
