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).
