  1. Abbreviations: BM+, biomarker positive; BM−, biomarker negative; DAS28, Disease Activity Score; DMARD, disease-modifying antirheumatic drug; IR, inadequate responder; LM, LITHE and MEASURE; LOT, LITHE, OPTION, and TOWARD; SNP, single-nucleotide polymorphism.
  2. Placebo-corrected remission rates and frequency are shown from patients carrying polymorphisms (biomarker positive) and those not carrying the polymorphisms (biomarker negative). Delta (Δ) represents the difference in remission rate between BM+ and BM−. Only combinations yielding the best Δ for each model are shown. Only 8 mg kg−1 tocilizumab-treated patients were considered in this analysis owing to the far higher remission rates observed with this dose.28
