Using univariate analysis, 3 predictive factors for being a responder were identified individually (the other tested variables did not reach statistical significance in predicting treatment outcomes): IGIc–IH1 at the end of the 3 mg/kg/day regimen (OR = 22.9, 95% CI [1.2–1844.1], p = 0.026), a treatment duration of at least 3.5 months at 3 mg/kg/day (OR = 17.5, 95% CI [1.22–250.37], p = 0.041), and of at least 7 months at doses > 3mg/kg/day, ranging from 3.75 to 4 mg/kg/day (OR = 17.5, 95% CI [1.22–250.37], p = 0.041).
