Hierarchical item ordering with item locations (± 95% CIs) on the y-axis (negative values = less dysautonomia) in this study (Sweden; blue dots/numbers) and a previous Spanish study [11] (Spain; red dots/numbers). Item 10 was excluded in the Spanish study [11]. Significant differences in item locations between the Spanish and this study were found for items 3, 5–7, 12, 16–18, and 20. Items are hierarchically ordered from the easiest (to the left) to the most severe (to the right) items.
