Methods
	RCT
	Location : Multicenter / Brazil Follow-up duration (days): 28
Inclusion criteria	•Age ≥18 years old •Probable or confirmed infection by SARS-CoV2 •Intubated and mechanically ventilated •Moderate or severe ARDS according to Berlin criteria3 (Partial pressure of arterialoxygen to the fraction of inspired oxygen (PaO2:FiO2) ratio of 200 or less, with positiveend expiratory pressure (PEEP) of at least 5 cm of water, bilateral opacities andrespiratory failure not fully explained by heart failure or fluid overload) •Within 48 hours of meeting criteria for moderate or severe ARDS
Exclusion criteria	•Pregnancy or active lactation •Known history of dexamethasone allergy •Corticosteroids use in non hospitalized patients in the past 15 days •Indication for corticosteroids use for other clinical conditions (e.g refractory septicshock) •Patients who used corticosteroids during hospital stay for more than one day •Use of immunosuppressive drugs •Cytotoxic chemotherapy in the past 21 days •Neutropenia due to hematological or solid malignancies with bone marrow invasion •Patients expected to die in the next 24 hours •Consent refusal for participation
Interventions
	Treatment Dexamethasone (20mg D1-D5, 10mg D6-D10) Co-Intervention: Standard care Duration : 10 days or ICU discharge
	Control Standard care Definition of Standard care: Each study center was encouraged to follow the best practice guidelines and their institutional protocol for the care of critically ill patients with COVID-19. All clinical interventions, such as use of antibiotics, ventilatory strategy, laboratory testing, and hemodynamic management were left at the discretion of the ICU team for both groups.
Participants
	Randomized 299 participants (n₁=151 / n₂= 148)
	Characteristics of participants N=299 Mean age : 61.4 187 males Severity : Mild: n=0 / Moderate: n=0/ Severe: n=0 Critical: n=299
Primary outcome
	In the register Yes
	In the report Ventilator-free days during the first 28 days, defined as the number of days alive and free from mechanical ventilation for at least 48 consecutive hours.
Documents avalaible	Protocol Yes. In English Statistical plan Yes Data-sharing stated Yes
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	In addition to all available versions of the published article, the study registry, statistical analysis plan and protocol were used in data extraction and risk of bias assessment. The study was terminated early. As a result, the target sample size (350) was not achieved. Quote:
