Fig 1 Smoothed function and 95% confidence band (dashed lines) for the effect of BTCs on the risk of a severe allergic reaction (grade III or IV) after the index field sting (final multivariate model). Odds ratios refer to those of the median of tryptase concentration. The odds ratio of the latter has been set at 1.

Fig 2 ROC curve for the final multivariate GAM predicting the risk of a severe allergic reaction (grade III or IV) after the index field sting.

Fig 3 Correction factor for BTCs. A correction factor is required to account for the patient's tryptase concentration to calculate the predicted risk, p, for a severe anaphylactic reaction in an individual patient (see the Methods section). The correction factor can be derived manually by determining the intersection of the tryptase concentration with the graph.
