Proportions of patients with a PGA rating of “good”, “excellent” or “cleared” by visit after (a) re-treatment with efalizumab (RT period*; ITT population, N = 113) or (b) transition to an alternative anti-psoriasis agent (TT period; ITT population, N = 68). *Patients had completed the FT period and responded but opted to enter the OB period rather than continue treatment with efalizumab; efalizumab treatment was restarted when their psoriasis began to worsen during the OB period. Patients had completed the FT period but had not responded and received treatment with another approved anti-psoriasis medication. FT = first-treatment; ITT = intention to treat; OB = observation; PGA = Physician Global Assessment; RT = re-treatment; TT = transition-treatment.
