Repeated measures analysis of covariance of the DCS (A), DRTSS (B) and DRMS (C) per year of the study (FAS _{Year 1–5} ). ^ap < 0.0001, ^bp < 0.0005, ^cp < 0.001, ^dp < 0.005, ^ep < 0.01, ^fp < 0.05 for comparison vs placebo. DCS, daily combined score; DRMS, daily rescue medication score; DRTSS, daily rhinoconjunctivitis total symptom score; FAS, full analysis set; IR, index of reactivity; LS, least squares; SE, standard error.
