Figure 2. Disease control* by baseline characteristics subgroups at week 52, based on IBA assessment (mITT population^†; N=263). Note: OR (95% CI) and p value are from a logistic regression model with covariates: baseline SLEDAI-2K, baseline immunosuppressants, baseline prednisone-equivalent dose and treatment group (however, covariates were excluded from the corresponding subgroup models, for example, baseline SLEDAI-2K was not included in analysis by baseline SLEDAI-2K). *Disease control is defined as a SLEDAI-2K score ≤2 achieved without immunosuppressants and with a prednisone-equivalent dose of ≤5 mg/day. ^†mITT population excludes 29 patients from the BEL/ST group, due to IBAs being potentially unblinded. BEL, belimumab; BLyS, B-lymphocyte stimulator; C3/4, complement 3/4; IBA, independent blinded assessor; mITT, modified intention-to-treat; PBO, placebo; RTX, rituximab; SLEDAI-2K, SLE Disease Activity Index-2000; SLE, systemic lupus erythematosus; ST, standard therapy.
