However, in terms of intensity of sensitization as measured by the size of the skin response, in SPT positive patients, no significant differences between allergic adults and children were noted (two way ANOVA p > 0.05); whereas, as expected, highly significant values were obtained between allergic and non-allergic adults ( p <0.001), and between allergic children and non-allergic adults ( p <0.0001) (Fig. 2 ).
