9. Health Literacy: We think you did a very good job explaining the risk in multiple ways – including both numbers and images. However, one number really jumped out at me. In the group with a 0.1% benefit and a 1% harm, 50% of people still wanted a CT scan. We had explicitly told patient that their chance of harm was 10x their chance of benefit, and they still wanted to be scanned. We think that number needs attention. Does it mean that your participants really didn’t understand the numbers you were giving them? Is it just a representation of the harms and benefits being qualitatively different (the benefit is immediate whereas the harm is delayed)? Or is there something else going on, because we find that number shocking.
