2.4 | Study quality assessment
Two reviewers (Xiaohong Wu and Zhoushan Feng) independently evaluated
data in randomized studies using the Cochrane “Risk of Bias Assessment
Tool” 13. Parameters for evaluation were as follows:
adequacy of random sequence generation, allocation concealment, blinding
of the caregivers and the assessors, incomplete outcome data reporting,
and selective reporting. Discrepancies were settled by discussion and
consensus.
