“✓”: guideline explicitly mentions evidence or outcome. Empty cell: guideline does not explicitly mention evidence or outcome. ^#: includes guidelines which only provided recommendations against remdesivir or recommended against remdesivir for at least one disease severity category and reported insufficient evidence for any other categories.

Abbreviations: ICU: intensive care unit; IMV: invasive mechanical ventilation; NCT: National Clinical Trial; NR: not reported; RCT: randomised controlled trial. Other outcomes considered: ^a: ICU length of stay was considered; however, published data precluded the pooling of trials for ICU length. Need for oxygen support was considered. Clinical improvement outcomes were considered. ^b: septic shock within 28 or 30 days; acute respiratory failure or acute respiratory distress syndrome (ARDS) within 28 and 30 days. ^c: clinical improvement at Day 15, clinical status distribution on Day 11+Day 14. ^d: additional end-points which were searched for by the guideline development committee but were either not studied or data were not found in an extractable format were: deterioration in those not requiring ventilation at start of treatment; requirement for oxygen; hospital admission; ICU length of stay; need for noninvasive ventilation; hospital length of stay; severity of symptoms; improvement in oxygen saturations or arterial blood gases; relapse and duration of fever. ^e: viral clearance (7 days); acute kidney injury; delirium; time to clinical improvement; duration of ventilation. ^f: lack of benefit in patients using IMV. ^g: clinical worsening: new need for noninvasive mechanical ventilation or high-flow oxygen at day 28; clinical worsening: new need for oxygen by mask or nasal prongs at day 28; quality of life. ^h: progression to oxygen therapy; progression to noninvasive ventilation or high-flow oxygen.
