Definition of terms
We defined AAR as symptoms induced by the unintended ingestion of an
allergic food. Cases of intentional ingestion of food that was meant to
be ingested or cases of symptoms due to ingestion in accordance with a
pediatrician’s instruction at home after passing the OFC were excluded.
Children with low-dose reactivity were defined as those who reacted to
low-dose OFCs or experienced allergic symptoms upon ingesting a low dose
or less of the allergic food within 2 years preceding the study
initiation. Those who passed the low-dose OFC and reacted to a dose
higher than the low dose within 2 years preceding the study initiation
were defined as those with low-dose tolerance.
