Figure 1.

Monthly incidence of food sensitization and allergy according to age and fish oil use. The upper part of each bar (lighter colour) shows the incidence of sensitization, diagnosed during the indicated age span, that is not accompanied by a positive double‐blind placebo‐controlled food challenge (DBPCFC) outcome, and the lower part (darker colour) shows the incidence of sensitization followed by a positive DBPCFC outcome. The numbers above the bars indicate the size of each reference group. On average, regular fish oil intake lowered the incidence of sensitization by a factor of 2.0 (P = .006) and DBPCFC‐confirmed allergy by a factor of 1.7 (nonsignificant, P = .095).
