Best-worst scaling relative bother estimates (N = 200). The = symbol between two weights indicates that those two weights are not statistically significantly different from each other (P < 0.05), and the ≠ symbol indicates that those two weights are statistically significantly different from each other. For example, 1 out of 100 (1%) risk of dying because of the operation is statistically significantly different from 1 out of 100 (1%) risk of damage to the nerves that control the vocal cords because of the operation, whereas 1 out of 100 (1%) risk of damage to the nerves that control the vocal cords because of the operation is not statistically significantly different from 2 out of 100 (2%) risk of having a seizure or convulsions. The bars surrounding each mean importance weight denote the 95% confidence interval about the point estimate
