Characteristics of the study population.
Table 3.
Percentage of the study population fulfilling the criteria proposed to define mast cell activation syndrome (for references, see text) when all other diagnoses that could better explain the full range and chronicity of the findings in the case have been excluded.
Table 4.
Percentage of the study population fulfilling the criteria proposed to define systemic mastocytosis (for references, see text) when all other diagnoses that could better explain the full range and chronicity of the findings in the case have been excluded.
