Assessment criteriaa

Methodological outcome reporting (based on MOMENT criteria [20])

1) Is the primary outcome clearly stated (in the method section)?

2) Is the primary outcome clearly defined (method section/protocol/register) so that another researcher would be able to reproduce its measurement?

3) Are the secondary outcomes clearly stated (in the method section)?

4) Are the secondary outcomes clearly defined (method section/protocol/register)?

5) Do the authors provide a rational for the use of the outcomes they have selected?

6.1) Are all defined primary outcomes and secondary outcomes reported which are defined in the method section?

6.2) Are reported outcomes limited to the outcomes defined (in the method section)?

Trial registration

7.1) Was the trial prospectively registered?

7.2) Are all (registered) primary and secondary outcomes reported?

7.3) Are reported outcomes limited to those registered?

7.4) Is there no sign of selective outcome reporting (e.g., change in primary or secondary outcome, new primary outcome, omission of primary outcome)?
