Anaphylaxis hospitalization rates for residents of New York and Florida between 1996 and 2005. Rates among New York children and adolescents (NY-C) and New York adults (NY-A) are reported along with rates among Florida children and adolescents (FL-C) and Florida adults (FL-A). Children and adolescents were 0 to 19 years of age, and adults were 20 years of age and older. Time trends were evaluated by entering the discharge year as a continuous variable in negative binomial regression models. ^aThe P values are for change in rate for each 1-year increase in discharge year from a negative binomial regression model
