Interventions
	Treatment Standard care *
	Control Tocilizumab ( / )
Participants
	Randomized 88 participants (n₁=29 / n₂= 59)
	Characteristics of participants N=88 Mean age : 58.5 48 males Severity : Mild: n=0 / Moderate: n=59/ Severe: n=20 Critical: n=1
Primary outcome
	In the register Clinical status at day 28 [ Time Frame: day 28 ](assessed using 7-category ordinal scale) 7 death 6 in ICU with ECMO/ mechanical ventilation 5 in ICU, no ECMO/ mechanical ventilation 4 in hospital, not ICU, needs supplementary oxygen 3 in hospital, not ICU, no supplementary oxygen 2 not in hospital, but not back to normal 1 not in hospital, back to normal
	In the report The primary endpoint was clinical status at day 28 assessed using a seven-category ordinal scale, where 1 is at home, normal daily activities; 2 is at home, assistance needed; 3 is hospitalized, no supplemental oxygen; 4 is hospitalized (non-ICU), receiving supplemental oxygen; 5 is in ICU, no invasive mechanical ventilation (IMV); 6 is in ICU receiving IMV and/or extracorporeal membrane oxygenation; and 7 is dead.

Risk of bias Overall The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review	Some concerns
General comment	Data presented was originally extracted from study registry and The WHO Rapid Evidence Appraisal for COVID-19 Therapies (REACT) Working Group "Association Between Administration of IL-6 Antagonists and Mortality Among Patients Hospitalized for COVID-19: A Meta-analysis." JAMA. 2021;326(6):499–518. On April 14, 2022, the extraction and risk of bias assessments were updated with information from the published article. There is no change from the trial registration in the intervention and control treatments. The registry primary outcome reflects the reported primary outcome. Of note: the outcomes Mortality (D60 or more) and Time to death were not reported in the 2022 publication and thus are the original extractions from The WHO Rapid Evidence Appraisal for COVID-19 Therapies (REACT) Working Group "Association Between Administration of IL-6 Antagonists and Mortality Among Patients Hospitalized for COVID-19: A Meta-analysis." JAMA. 2021;326(6):499–518. Furthermore, we extracted data reported as severe adverse events in the published report under our serious adverse events outcome.
