The elicitor was not specified in 423 (6%) patients. Rare elicitors are not reported in detail.
Statistical analysis was performed with Chi2 test including post-hoc corrections. Significant differences were given in comparison to adults between 18 and 64 years of age. Food items reported < 10 times in the whole study are not listed in detail. PPI, proton pump inhibitor.
