Evaluating prodrome dimensions
Patients were asked to rate their
experience with prodromes in different dimensions measured on a Likert
scale (Visual Analog Scale, VAS) of 0 to 10cm. Analysis of variance
(ANOVA) demonstrated a significant and consistent difference between
dimensions of prodromes in various
locations (clusters). Paired t-test showed significant differences
between the dimensions of prodromes and attacks across all clusters
(Figure 2). Generally, the severity of prodromes in the abdomen and the
extremities exceeded the other clusters (urogenital, facial,
oropharyngeal). It should be noted that mean severity of prodromes was
much less (by half) as compared to attacks across all dimensions (pain,
severity and functionality) in all the pre-specified domains (clusters)
(Figure 2).
