主要终点
Skin wheal measure for each tested solution. For each allergen tested, 2 variables, positive SPT and negative SPT were defined. A SPT reaction was considered positive when the mean wheal diameter was >3 mm. A SPT reaction ≤3 mm was considered negative.

结局指标

主要结局

Skin wheal measure for each tested solution. For each allergen tested, 2 variables, positive SPT and negative SPT were defined. A SPT reaction was considered positive when the mean wheal diameter was >3 mm. A SPT reaction ≤3 mm was considered negative.

时间窗: For each subject, the study consisted in one visit of about 60 minutes including skin prick-test and collection of blood sample for IgE determination.

次要结局

  • One of the secondary measurement was the wheal diameter for each allergen.(SPT measurements were performed after the study visit, an expected average of 1 week.)
