Figure 2.
The bars (brange=attack, blue=prodrome) represent the intensity of
attacks and prodromes in different body locations (clusters). HAE
patients were asked to rate their experience with prodromes on a visual
analog scale (VAS) scale ranging from 0 to 10cm. Intensities of the
prodromes were significantly less than those of the attacks, as
demonstrated for each scalable dimension (pain, severity, impairment,
functionality).
