| RECOVERY |
Low risk of bias |
Participants were randomised via web‐based randomisation and the allocation sequence was concealed. There are no baseline differences that would suggest a problem with randomisation. |
High risk of bias |
Both participants and those delivering the intervention were aware of intervention received and nearly all participants received assigned intervention. The analysis was appropriate. Because of no standard treatment for COVID‐19, control group may have received concomitant treatment more quickly. |
Low risk of bias |
Data for this outcome was available for all 9785 participants randomised. |
Low risk of bias |
The measurement of the outcome was appropriate and it is unlikely that it differed between intervention groups. It was unclear whether outcome assessors were unaware of the intervention received, but it is unlikely that knowledge of intervention received could have affected outcome measurement. |
Low risk of bias |
The outcome was pre‐specified and there is no indication for selective reporting. |
High risk of bias |
For this outcome, there is a low risk of bias due to the randomisation process, due to missing outcomes, due to measurement of the outcome and due to selection of reported results. However, there is high risk of bias due to deviations from the intended interventions. |
