Notes:
- Wild type refers to recombinant, unmodified proteins.
- P-value reflects comparison of not reactive to reactive at baseline using the exact Wilcoxon test.
- Results for wild type, native, and modified proteins represent OD assessments at 1:100 dilutions
- Ara h 1, Ara h 2, and Ara h 3 were analyzed with ImmunoCAP at baseline only and not at Week 20.
