2 Fig 1 Percentages of patients experiencing (A) CIU/CSU clinical worsening defined by UAS7,* and (B) Dermatology Life Quality Index (DLQI) worsening† were significantly lower in omalizumab- vs placebo-treated patients. *UAS7 of at least 12 for 2 consecutive weeks. †At least 3-point increase in the DLQI score.

5 Fig E2 Time to CIU/CSU clinical worsening.* *UAS7 of ≥12 for 2 consecutive weeks. Time 0 represents 4 weeks post omalizumab dosing for placebo patients. +Censored indicates an individual patient dropping out of the analysis.
