Table 1. Operationalization of internal validity criteria

1. Concealment of allocation
MET: Use of centralised (e.g. group assignment by a central office unaware of subject characteristics); on‐site computer system combined with group assignments in a locked unreadable computer file that could be accessed only after entering characteristics of an enrolled subject; sequentially numbered, sealed, opaque envelopes; i.e. the randomizations was independent of provider and investigator.
UNCLEAR: Concealment approach was not reported and could not be verified by contacting the investigators
NOT MET: Included alternation, case record numbers, dates of birth, day of the week, and any allocation procedure that was entirely transparent before assignment, such as an open list of random numbers of assignments

2. Co‐interventions
MET: Interventions other than bed rest avoided, or used similarly across comparison groups
UNCLEAR: Use of interventions other than bed rest not reported and could not be verified by contacting the investigators
NOT MET: Dissimilar use of interventions other than bed rest

3. Intention‐to‐treat analysis or losses to follow‐up
MET: Intention to treat analysis performed or possible AND losses to follow‐up less than 20% and equally distributed between comparison groups
UNCLEAR: Exclusion reported, losses to follow‐up less than 20% and equally distributed between comparison groups
NOT MET: Exclusion not reported and could not be verified by contacting the investigators, losses to follow‐up greater than 20%

4. Outcome assessment
MET: Assessor unaware of the assigned treatment when collecting outcome measures
UNCLEAR: Blinding of assessor not reported and could not be verified by contacting the investigators
NOT MET: Assessor aware of the assigned treatment when collecting outcome measures
