To minimise bias in interpretation of the tool, a small
sample of unrelated studies will be assessed. Inconsistency
in scoring will be reviewed, and a consensus reached prior
to the analysis of the review studies. The tool will be used
to judge and report whether a trial is deemed to be at
‘high’, ‘low’ or ‘uncertain’ risk of bias. A summary statement
regarding the quality of the data included in the review
and a narrative account of any serious flaws will be
reported.
