Summary of risk of bias for RCTs (RevMan 5.3).
Red: High risk; Yellow: Unclear risk; Green: Low risk * Because the studies compared bed rest versus ambulation, it is too easy for the patients to find out which group they are in. So it is not likely to fulfill the requirement of blinding of participants. ** Details about the reasons for this assessment are listed in the supporting information S3 Table.
