*
Food reintroductions were conducted in 75% of the 69 patients who had both SPT and APT performed at the CCED.
†
Diet therapies were compared statistically using the X2 test or Fisher’s exact test for discrete variables and the Kruskal-Wallis test for continuous variables. No significant differences for pairwise comparisons were detected.
‡
SPT, skin prick test;
§
APT, atopy patch test;

n/a = not applicable.
