Fig. 1 Mean URSxs are displayed relative to test results. A mean symptom score of 0.5 or more (dashed line ) was considered positive. Group mean values are designated by the solid lines . P values comparing positive and negative test scores were less than .0001 for SPTs, .35 for IDSTs, and less than .0001 for RASTs. Pos , Positive; Neg , negative.

Fig. 2 Mean LRSxs are displayed relative to test results. A mean symptom score of 0.4 or more (dashed line ) was considered positive. Group mean values are designated by the solid lines . P values comparing positive and negative test scores were less than .0001 for SPTs, .89 for IDSTs, and less than .0001 for RASTs. Pos , Positive; Neg , negative.

Fig. 3 Maximum changes in FEV1 values are displayed relative to test results. A maximum fall of 15% or more (dashed line ) was considered positive. Group mean values are designated by the solid lines . P values comparing positive and negative test results were less than .0001 for SPTs, .63 for IDSTs, and less than .0001 for RASTs. Pos , Positive; Neg , negative. Journal of Allergy and Clinical Immunology 1999 103, 773-779DOI: (10.1016/S0091-6749(99)70419-7) Copyright © 1999 Mosby, Inc. Terms and Conditions
