Correlations between attacks and prodromes
Highly significant correlations were found between the dimensions of
prodromes and attacks (i.e. functionality in the abdominal cluster, r=
.68, p < 0.001, Fig 3a). In all clusters, except for the
extremities, positive and significant correlations were found between
the severity of the prodromes and the attacks. It shoulc be noted that
in most clusters, as the severity of the prodromes increased, so does
the severity of the attacks (Figure 3 a-d).
