Table 6. Longitudinal association of delta CARAT and ACQ scores with delta pollen counts in patients with a history of clinical reactivity to pollen.

	Delta pollen counts birch/grass
	Period 1 (n=49)	Period 2 (n=41)
Delta CARAT score	0.32	0.11
Delta ACQ score	0.10	0.06

All Pearson correlations were significant (P<0.05). Period 1 represents the 4-week period between T1 and T2, period 2 represents the 4-week period between T2 and T3.

Abbreviations: ACQ, Asthma Control Questionnaire; CARAT, Control of Allergic Rhinitis and Asthma Test.
