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 the pre-print article, the trial registry was used in data extraction and risk of bias assessment. Significant changes were made to the trial registration after the end of the study recruitment: it was changed from an unblinded, non-randomized study to a triple blinded, randomized trial; inclusion criteria 'O2 saturation of less than 92 in room air' and 'Hospitalized patients' were added; the methylprednisolone regimen was changed; the comparator was changed from standard care to dexamethasone; the sample size was increased; the primary and secondary outcome measures were changed from PAO2/fio2 (primary) and oxygen saturation, CT scan and clinical follow-up (secondary) to all-cause mortality and clinical status (primary) and mechanical ventilation, ICU admission and length of hospital stay (secondary).
