Effect of baseline blood eosinophil counts and serum IgE concentrations on annual asthma exacerbation rates for patients receiving placebo (full analysis set)

Serum IgE concentration (kU/L)	Crude AER
	Baseline blood eosinophil count (cells/µL)
	< 150	≥ 150 to < 300	≥ 300 to < 450	≥ 450
< 62.0	1.25 (n = 53)	0.91 (n = 57)	1.28 (n = 32)	1.44 (n = 43)
≥ 62.0 to < 176.2	1.57 (n = 34)	0.94 (n = 45)	1.15 (n = 46)	1.84 (n = 66)
≥ 176.2 to < 453.4	1.10 (n = 30)	1.93 (n = 42)	1.19 (n = 45)	1.38 (n = 80)
≥ 453.4	0.80 (n = 29)	0.84 (n = 31)	1.10 (n = 39)	1.33 (n = 90)
