Figure 2.

Histogram of the responses for the question "How was the scanning procedure?". Participants responded on a scale from 1 (very comfortable) to 7 (very uncomfortable). Y-axis depicts the proportion of cases who chose a given response category. Healthy subjects as well as patients rated the procedure on average as being comfortable (ps < .01 when compared to the middle category of 4). Mean ratings of healthy subjects and patients did not differ significantly.
