Note: The risk of bias by domain corresponds to the highest risk of bias among outcomes by domain.
The overall risk of bias corresponds to the overall highest risk of bias assessed among outcomes.
| Bias | Author's judgement | Support for judgement |
| Randomization |
Some concerns |
Quote: “Patients were randomly assigned.”
Comment: Allocation sequence probably random. No information on allocation concealment. |
| Deviations from intervention |
Some concerns |
Quote: “Open label”
Comment: Unblinded study (participants and personnel/carers) Deviations from intended intervention arising because of the study context: No participant cross-over. No information on administration of co-interventions of interest: biologics. Antivirals and corticosteroids were reported and balanced between groups. Hence, no information on whether deviations arose because of the trial context. Our analysis for the binary outcome is an intention-to-treat analysis. This method was considered appropriate to estimate the effect of assignment to intervention. Risk assessed to be some concerns for the outcome: Mortality (D28). |
| Missing outcome data |
Low |
Comment: 100 participants randomized; 100 participants analyzed.
Data available for all participants randomized. Risk assessed to be low for the outcome: Mortality (D28). |
| Measurement of the outcome |
Low |
Comment: Method of measuring the outcome probably appropriate.
Measurement or ascertainment of outcome probably does not differ between groups. Unblinded study (outcome assessor) MORTALITY Mortality is an observer-reported outcome not involving judgement. Risk assessed to be low for the outcomes: Mortality (D28). |
| Selection of the reported results |
Some concerns |
Comment: The protocol, statistical analysis plan and registry were not available.
No information on whether the result was selected from multiple outcome measurements or analyses of the data. No information on whether the trial was analyzed as pre-specified. Risk assessed to be some concerns for the outcome: Mortality (D28). |
