a
Pearson Chi2-test.
b
Fisher's exact test.
c
Independent samples t-test.
d
Yes, if positive reaction by skin prick test toward a minimum of one common aeroallergen.
e
Yes, if positive reaction by skin prick test toward raw snow crab, cooked snow crab and in some participants cooking water from snow crab.
f
Yes, if positive reaction by skin prick test toward raw or cooked Northern Prawn and in some participants cooking water from Northern Prawn.
g
Yes, if positive reaction by skin prick test toward raw cod or turbot (one participant) or RAST test toward cod (four participants).
h
Yes if positive RAST test toward Anisakis simplex. Bold value indicates p < 0.05.
