Levels of allergic sensitivity for patients with allergic rhinitis to four grass pollen extracts in different regions measured by skin prick test diameters [(a) QLD n = 127–130; (d) WA n = 48; (g) NSW n = 18–21; (j) SA n = 69–72], serum‐specific IgE concentrations to grass pollen extract [(b) QLD n = 98; (e) WA n = 27; (h) NSW n = 26; (k) SA n = 34] and serum‐specific IgE concentrations to purified group 1 allergen components [(c) QLD n = 76 or 77; (f) WA n = 15–18; (i) NSW n = 14–23; (l) SA n = 28–31]. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001 and ****P ≤ 0.0001.
