Selected patients were skin tested with allergens mixed with AS. Controls included allergens alone and saline. Means and standard deviations, as well as P-values, of data (clinical scores, see Methods) collected from the 50 patients are presented. P-values were determined using an unpaired two-tailed Student's t-test. A P-value of < 0.05 was considered statistically significant. Notice that AS markedly reduced skin test reactions to the allergens tested.
