Flow sheet of the algorithm. The numbers in each box correspond to the number of patients in the risk assessment of possible reactions to soybean/lupine/fresh green pea/blanched green pea, respectively. Eventually, the patients are divided into high- or low-risk groups. Pea challenges were only performed with fresh green pea. The outcome of the fresh pea challenge was used to classify the patients as either high or low risk for both fresh and blanched green pea.
