Soy allergy
Three studies for SPT [65, 100, 158, 180] met the inclusion criteria for soy allergy meta-analyses, with pooled sensitivity of 47% and specificity of 79% (Table 2 ). IgE to soy [100, 121, 151, 180] and Gly m 4 [64, 100, 121] had sensitivities of 73% and 61% with specificities of 75% and 69% respectively. For SPT to soy the maximum specificity was ≥ 90% (Table S5 and S6 ).
