Koskenvuo 2019

Low risk of bias

Generation of randomisation sequence and concealment of allocation were adequate. There was no baseline imbalance that would suggest a problem with randomisation.

Low risk of bias

Both participants and those delivering the intervention were aware of intervention received. There were no deviations from intervention.

Low risk of bias

95% of randomised patients were analysed in the modified intention‐to‐treat analysis.

Low risk of bias

Patients are discharged from inpatient therapy after recovery. The timing of discharge is influenced by many factors. Therefore, knowledge about the intervention has little to no influence on the assessment of this outcome.

Low risk of bias

The trial was registered with ClinicalTrials.gov (NCT02652637) and EudraCT (2015‐004559‐38).

Low risk of bias

Low risk of bias in all domains.
