Figure 9 is a bar graph depicting the distribution of allergens in the SCIT studies. It shows the most frequent allergen was dust mite (21 studies), followed by the studies with multiple allergen (15 studies), ragweed (6 studies), and tree (tree mix or trees, 6 studies). All the other allergens were similarly distributed (5 studies or less per allergen). We had just one study with rye and one study with dog allergens.
