Mean (95% confidence interval) and median utility indices with and without symptoms/flares in the previous year; significance of the differences between symptoms/no symptoms and flares/no flares: (-test and Mann-Whitney test).
AUC: area under the ROC curve dependent on the information regarding current symptoms or flares in the previous year (95% confidence interval).
