Interventions
	Treatment Tofacitinib 10 mg orally twice a day for up to 14 days or until hospital discharge, whichever was earlier
	Control Placebo
Participants
	Randomized participants : Tofacitinib =144 Placebo=145
	Characteristics of participants N= 289 Mean age : NR 188 males Severity : Mild: n=71 / Moderate: n=181 / Severe: n=37 Critical: n=0 Number of vaccinated participants: NR
Primary outcome
	In the register Death or respiratory failure until Day 28 [ Time Frame: 28 days ]

Documents available	Protocol Yes. In English Statistical plan Yes Data-sharing willing stated in the publication: N
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	Low
General comment	In addition to the published article with supplementary appendices, the protocol with statistical analysis plan and prospective study registry were used in data extraction and risk of bias assessment. The study achieved the target sample size specified in the trial registry. There no substantive differences between the published article and the registry or protocol in population, procedures, outcomes or intervention and control treatments.
