(Fig. S5 in the Supplementary Appendix shows contour diagrams of the distribution of peanut-specific IgE in relation to peanut-specific IgG4 over time in participants who met the per-protocol criteria. Fig. S5 also shows that levels of peanut-specific IgE did not exceed 100.0 kU per liter in the peanut-consumption group. Peanut-specific IgG4 lrvels in this group rose early and continued to increase through 60 months of age.)
