  • *Responder rates (percentages), the difference in estimates and associated 95% CIs were weighted and calculated using a stratified Cochran-Mantel-Haenszel approach, with stratification factors SLEDAI-2K score at screening, day 1 glucocorticoid dose, type I IFN gene signature test result at screening and study.

  • †OR (95% CI and p value) are based on a logistic regression with same stratification factors.
