IL6 and COVID-19: Moreover, results of RCT REMAP-CAP comparing anti-IL-6 (plus corticosteroid) vs SoC in severe-to-critical COVID-19 cases showed higher in-hospital survival (aOR 1.64 95%CrI 1.14, 2.35; posterior probability of superiority 99.6%) and higher organ support-free days (aOR 1.64, 95%CrI 1.25, 2.14, posterior probability of superiority >99.9%) in TCZ recipients [23].
