Functionality
The mean in affected functionality was higher in the abdominal attacks
as compared to the other clusters. Additionally, significant differences
were found between the abdominal and the three other clusters
(urogenital, facial, oropharyngeal) and between the
extremities to the other clusters.
In particular, paired tests showed a difference between the abdomen and
extremities and other 3 clusters.
As a rule, attacks experienced in the abdomen were consistently
perceived as extremely challenging for the study subjects. The intensity
of pain in the attacks was very high and reached a level of 7-8 on a
scale of 0-10 (Fig 2). The standard deviations in dimensions of the
attacks were relatively small, which indicates a consistency in
individual observations across all the clusters.
