    • Negative: 0% intervention arm, 0.7% control arm

    • Unclear: 4.6% intervention arm, 3.4% control arm

  • Ethnicity: not reported

  • Number of participants (recruited/allocated/evaluated): 545/151 intervention group and 148 control group/151 intervention group and 148 control group

  • Severity of condition according to study definition: all participants were mechanically ventilated

  • Severity of condition according to WHO score: severe 7‐9

  • Co‐morbidities: hypertension, diabetes, obesity, heart failure, chronic kidney failure

  • Inclusion criteria:

    • At least 18 years old

    • Confirmed or suspected COVID‐19 infection

    • Receiving mechanical ventilation within 48 hours of meeting criteria for moderate to severe ARDS with partial pressure of arterial blood oxygen to fraction of inspired oxygen (PaO2:FIO2) ratio of 200 or less

  • Exclusion criteria:

    • Pregnancy or active lactation

    • Known history of dexamethasone allergy

    • Corticosteroid use in the past 15 days for non‐hospitalised patients

    • Use of corticosteroids during the present hospital stay for more than 1 day

    • Indication for corticosteroid use for other clinical conditions (eg, refractory septic shock)

    • Use of immunosuppressive drugs

    • Cytotoxic chemotherapy in the past 21 days

    • Neutropenia due to hematological or solid malignancies with bone marrow invasion

    • Consent refusal

    • Expected death in the next 24 hours

  • Previous treatments: no

Interventions Treatment details of intervention group (e.g dose, route of administration, number of doses):
  • Type of corticosteroid: dexamethasone

  • Dose: 20 mg once daily for 5 days, followed by 10 mg intravenously once daily for additional 5 days or until ICU discharge

  • Route of administration: intravenous


Treatment details of control group (e.g dose, route of administration, number of doses):  standard care
Concomitant therapy (e.g description of standard care): hydroxychloroquine, azithromycin, other antibiotics, oseltamivir
Duration of follow‐up: 28 days
Treatment cross‐overs: no
Compliance with assigned treatment
  • 25 deviations from protocol in the intervention arm (16.55%)

  • 1 patient received a corticosteroid other than dexamethasone

  • In the control arm, 52 patients received corticosteroids, of which 14 were protocol deviations (9.4%)

Outcomes Primary study outcome: number of days alive and free from mechanical ventilation for at least 48 consecutive hours
Review outcomes: Inpatient setting
  • All‐cause mortality at day 21, or longest observation period: reported

  • Improvement of clinical status during observation period:

    • Liberation from IMV in participants i.e. transition to WHO ≤ 6 if ≥ 7 at baseline (see Figure 1). If liberation was not available directly, death was used as a proxy for assumed non‐liberation counted together with participants alive and ventilated: reported

    • Ventilator‐free days and alive: reported

  • Worsening of clinical status during observation period:

    • Need for IMV i.e. transition to WHO 7‐9 if ≤ 6 at baseline (see Figure 1): reported

  • Need for dialysis (at up to 28 days): not reported

  • Quality of life, including fatigue and neurological status, assessed with standardised scales (e.g. WHOQOL‐100) at longest follow‐up available: not reported

  • Viral clearance, assessed with RT‐PCR test for SARS‐CoV‐2 at baseline, up to 3, 7, and 15 days: not reported

  • Serious adverse events: reported

  • Adverse events (any grade): reported

  • Hospital‐acquired infections: reported


Additional study outcomes: Sequential Organ Failure Assessment (SOFA) scores
